Tony @ Mamo Motorsports

Guys,

I have helped alot of you at this point with my ported LT1 / LT4 throttle bodies which IMO is one of the best bang for the buck upgrades you will ever experience. While that sounds like a convenient sales pitch, coming from a guy who places a high value on his reputation (and who has decades of experience in this industry) I simply wouldn't make a statement like that unless I felt it was true. When you factor in the gains versus cost and the 10-15 minute cake installation, it really just doesnt get any better at this price point (under $400 shipped to your door). Also the reality of the situation is my ported throttle body cures a problematic design issue with the OEM part....that's why this upgrade is such a significant improvement in responsiveness, drivability, and increases torque and horsepower output.

Getting on with the real reason I decided to start this thread, I recently received an email from one of my customers that was so detailed and well written I requested his permission to post it on the forums (he isn't a registered member on any of the car related forums yet).

Its very informative in my opinion and written from the point of view of the end user who was uncertain about exactly what he was going to experience when I mailed it to him but was looking forward to it based on all the good reviews he has read.

Here it is copied and pasted below exactly how I received it.....I think its a good read, especially helpful from the standpoint of a perspective buyer which is why I took the time to share.

Jim......once again....thanks for the well thought out email and for taking the time to share your experience with me

Cheers,
Tony

Tony,
I received your ported TB early this afternoon, installed it and spent the rest of the day driving my ZL1 all over hell's half acre to give my car and your TB a chance to get acquainted. Below is a synopsis of my driving impressions.

Review date: 09 June 2018
Wx: Sunny, Clear, Air Temp 90deg, Humidity 72%, Baro 30.02
Vehicle: 2018 ZL1 A10, 3100 miles, no modifications (except ported TB), Shell 93 pump gas, operated mostly in Sport Mode with occasional runs in Track Mode

Review Conditions: No effect on idle. Car started and ran as normal with a slight increase in audible S/C noise when revving. Drove the car for 127 miles varying throttle position from low speed lugging around town, idling in drive, idling in park, heat soaking twice after highway runs then starting up again and finally, several high-speed WOT runs. Specifically looked for how the car responded under part-throttle, moderate acceleration then backing off before resuming moderate throttle and rolling WOT at various speeds.

Impressions: The car never hesitated or bogged down under any of the conditions stated above. Throttle response was significantly smoother through the transition of part throttle to moderate or WOT. Previously, the car seemed to buck when stepping on the gas and then lunge forward. Transition is much smoother with less right foot pressure needed to get things going. The same is also true when backing off the throttle then stepping down again. This is very noticeable when exiting corners under part throttle then mashing it down. The bucking is all but absent making for a smooth and confidence-inspiring experience.

The closest thing I can relate this feeling to is my experience riding two very different motorcycles from Kawasaki; the n/a 900 Ninja and the GPZ 750 Turbo. Power from the Ninja mill was very linear and would build in a smooth, controlled manner. You could confidently throw it into a corner and then roll-on the throttle upon exit with no fear. On the other hand, the Turbo was either mildly sedate or with just a little more twist of the wrist, ferocious with stupid-fast acceleration and no in-between. The bike would buck as I tried to find the right throttle position. The ZL1 throttle feels similar in how it makes the car behave into and out of corners. Not anymore!

I feel more pressure against the seat when accelerating from a standstill and especially from low-speed to WOT jaunt. Power delivery is much more linear with speed building noticeably quicker. Not a huge difference but, a noticeable difference. Equally noticeable was how much quicker the car settled down into a steady-state after reaching speed. Whether it was 50mph or 3 x 50mph, once the car reached the desired speed it calmed right down and sailed smoothly along. The Boost Guage is more lively now, moving much quicker from vacuum to boost with just the slightest touch of the throttle.

A curious side-effect that jumped out at me was how long the car remained in 'Performance Mode' when pushed. The xmsn would hold a lower gear longer before shifting. I repeated this effect several times accelerating hard then decelerating just as hard while negotiating corners or running a straight section of road. The shift point is noticeably longer. Almost as if the car is begging for more right-foot fun and holding out a little more before finally calming down and up-shifting. I'm going to keep playing with this aspect and see what to make of it.

Last item of note is the amount of soot produced with the new TB. Previously, under hard acceleration, the inner tailpipes would be as black as the bottom of a mineshaft with a thick layer. Now, there is significantly less soot and even after multiple hard runs, I can still see chrome at the tips. There's still plenty of soot, just not anywhere near as much as before. This tells me the AFR has changed and the engine is running leaner but not so lean as to be of concern.

Summary: Tony, as you well know by now, your ported TB for the LT4 is a home run. A great piece of gear that delivers in all areas of performance. Well Done!

Regards,
Jim Aldridge

P.S. For 2017-18 ZL1 owners, the water deflector in the hood is really an air extractor when removed. Front end of the car really settles down at speed when it's removed!

I just installed mine on Saturday. I definitely noticed throttle improvement but I think the auto guys might be in the better camp when it comes to bucking and bogging. It's a lesser degree now on my M7 Z06, but not gone. I'm thinking the one true way to get rid of it is through a tune. But for now this $390 ported TB will work for me.

Tony, I installed your TB on my 2019 Z06 (M7) after the first 100 miles. It did eliminate most if not all of the throttle lag that I had. I had a reduced power mode pop up once upon start up, which was fixed by unplugging the MAF with the car off and plugging it back in. Since then I have had zero issues at all over the past 1000 miles.

I paired your throttle body with the BMS filter and the Corsa X pipe and have had zero issues. Throttle response is smooth and the car feels great!

Is there much of a benefit to installing the ported TB on an A8 car? I've not had any "stumbling" issues off idle except for when I'm in park and bump the gas occasionally before shutting it down. It's always nice to let the neighbors know when I'm home...

Thanks,
Aaron

Tony @ Mamo Motorsports

You had a few airflow mods (on the stock tune) so this wouldn't be totally out of the norm.....usually two upgrades fly under the radar.....you had three (which is slightly more likely to throw a code) but as you have experienced the computer did learn and your good to go. Sometimes you have to clear the code a few times in order to put enough miles and hot and cold starts on it but it seems you were good to go with only one.

A filter or CAI upgrade and my TB is pretty much plug and play....when you have a third mod (in your case the Xpipe), you may get the situation that you experienced. Note if you had a recurring issue where you constantly had to keep clearing the code I would have simply exchanged your TB for a slightly less aggressively ported unit to solve the problem but in your situation (and most) that wasn't necessary.

Glad to hear your enjoying the TB!!


Regarding auto vs manual and the gains experienced, I have gone over this numerous times in various threads but it's worth repeating.....in a nutshell.....ALL THE UPSIDES ARE THE SAME.

Your engine has no clue what transmission is bolted behind it.....all the perks of my ported TB are exactly the same including the 12- 15 RWTQ and 12-15 RWHP it adds as well.....the increase in throttle response, the removal of the lag off idle (which is simply masked more with the auto because there is no clutch pulling the engine down and less fancy foot work....LOL)....the large improvement in tip in throttle and the more linear intuitive power delivery.....its ALL there. The manual trans cars and the autos all reap the same benefits of this upgrade.

In fact I have helped many guys that have an A8 (who didnt realize they even had an issue) that simply wanted to try my product because of all the good reviews (knowing I offer a 30 day performance guarantee as well so no risk). Many of them took the time to email me back and let me know that now the car feels especially awesome with this upgrade and they didnt realize how bad it was until they felt how right it could be with the modified TB I offer.....a welcomed surprise on the upside for most.

While the manual trans guys are thrilled it helps remove/eliminate an issue that is more obvious (specifically the off idle lag), the A8 guys have been just as happy and as I mentioned more surprised mostly not realizing what they have been missing all along.

I encourage all of you running a stock LT1 or LT4 TB to try one of my modified units....its plug and play....no tune required....if your not totally stoked about the money you spent with me you have 30 days to return it for a full refund. Not too many opportunities in this hobby that offer you that type situation.....take advantage of it while you can. Also, clearly your not taking a flyer here....there must be a few hundred posts with extremely satisfied customers running my products. If your new to this hobby or the GM platform I recommend you Google my name if your unfamiliar with my background. I have been designing high performance cylinder heads, intake manifolds, and TB's for two decades and I basically specialize in the art of airflow. I should add that while I have designed cylinder heads and various airflow related products for alot of different brands over the years (even sport bikes), Im a "bowtie man" at heart and GM products make up 90% of the gear I specialize in.


Cheers,
Tony

Tony do you have any dyno data on the C7 Zo6 before & after you're TB install?? I would imagine you would given your reputation for thorough testing.

Tony @ Mamo Motorsports

Better than my testing perhaps is 3rd party independent testing.

This was done on the same day....same dyno.....the TB was literally swapped with the car on the rollers and tested once the quick install was completed.

Big gains under the curve....solid gains in peak numbers as well

Besides the huge improvement in throttle response and elimination (or massive improvement) of that dead zone in the pedal off idle, there are significant gains in both peak power and torque from this mod as well

Overall an incredible value for the dollars spent!!

Thanks Tony I am putting you're TB on my upgrade list

Another Mamo TB convert here. Installed the new TB last week and immediately noticed a difference in how my '16 A8 Z06 drives. Specifically, the jittery torque lag/surge I notice from on/off throttle is now gone. The car drives much smoother than before. This makes this mod alone worth the upgrade. The car almost drives like my previous NA Z06's in normal driving conditions. You obviously feel the SC kick in when you stab the throttle, but otherwise the car drives so much better. The throttle response is also much better, but the driving behavior of this car is clearly much improved.

Thanks Tony!

The T-man

Got mine installed
Wow...really woke the car up!
Super crisp throttle response, especially right off idle
And seems much more responsive all through rev range
And I'm w/ A8
you M7 guys shouldn't even think twice

FL KEYS ON

Had this ported TB on mine for about 7 months now and same experience here. C7 M7 Z06 too. It helps over stock TB but does not quite totally take away the annoying initial bogging. Perhaps a tune will totally remove the initial bogging, but not an option until after all warranties are exhausted .... even then not sure I'd wanna tune anyway. Give it a few fast revs before taking off is the norm.

Ordered the Mamo TB today, already have the Burger filter. Plan on stopping here (famous last words in my case). But really my 2016 Z06 has all the performance I need except for correcting a few issues. I am going in and have new pilot SS tires installed tomorrow to replace the cup tires that came on it and later this week to have the MRC update installed and get the re-aligned to the DSC Sport Specs. Will not install the Burger filter until the Mamo TB is delivered. Will report back impression of filter & Mamo TB.

Mr. Mamo -- your website appears to be just pictures? All product-specific data and ordering must be performed via phone call I assume?

Or perhaps I'm missing some link on your site?

Tony @ Mamo Motorsports

No....not at all.....website is still work in progress and Im WOT now just keeping up with orders!

While you can email or call me to process the order perhaps the easiest and fastest way to facilitate the purchase is to hit my website

www.mamomotorsports.com

Top right corner of home page you will see a pic of a credit card.....click on it and fill out all your info....its that simple. Insert 390.00 in the payment amount (that's the shipped price).

After your last name use a space and type LT4 (or LT1) to designate the correct TB. You will receive an email receipt of the transaction immediately and I will be notified of the payment at that exact same time.....pretty quick and straightforward. I will email you tracking info when Im ready to ship. Older orders take priority and ship first so the sooner you order the sooner it ships

Current lead times are two weeks or so

I will send it USPS priority in a well packed box

Regards,
Tony

I have the Mamo TB on my 2017 MN7 Z06...with a Burger Motorsports Filter and a Corsa X Pipe...

This combo really works for me with no CEL and is just great seat of the pants fun.

Tony is always there to answer any questions and is a maniac like the rest of us...

Tony- I’ll be getting a ZR1 in a couple of months (order was just picked up in the GM system)...will you have a Ported TB for ZR1’s?

Tony @ Mamo Motorsports

Let me know when you get the ZR1....I will order a new unit from GM and port it for you. You keep your stocker this way and we to play a bit with a few different iterations of the ported TB starting conservatively initially. Would love to help out and get into that market as well.

Awesome ride btw....the best out of the box Vette ever made offering a ton of potential in the aftermarket as well.



Cheers,
Tony

These 2 are my only engine mod's, they work very well together.
