Tony Mamo Ported TB installed
Received TB from Tony yesterday. Did installed this morning. Easy install with screwdriver, 7mm and 10mm sockets. l let car warm up and went for quick test drive. Temps were cold @ 29* and dry so traction was non-existent.
My thoughts: Throttle response seemed much better at tip in, when possible, roll in was smooth and linear and seemed improved over stock and no codes..
JMO, but no downside and Tony claims +10 HP, a plus and a satisfaction guarantee from Tony.
GL!

^^^Hi Gene,
I originally sought out the Katech ported TB to cure the lousy off idle throttle response my stock 2016 Z06-Z07-M7 exhibited in normal driving. By normal driving I mean leaving from a dead stop as if there is a cop watching you. Just normal let out the clutch and accelerate away from a dead stop. I was amazed how often I would kill the engine in this scenario. Never had any trouble in my C5 Z06 or any other stick car for that matter.
The Katech TB is a nice piece, and it did help the issue I was looking to solve. I have a background in machining, comparing the stock TB to the Katech I could tell there was certainly more that could be done to improve the throttle response off idle and overall airflow. The question is, how far can you go without getting a code.
Tony Mamo's reputation with the Cadillac LSX TBs is stellar, so I asked him about a C7 TB.
The first thing I noticed with the Mamo TB is the difference in shape and material removed. Quite frankly, based on the gap I saw between the throttle blade and the housing I thought the engine would never idle down. In fact I was so worried, I kept my hand on the the starter button ready to kill the engine right after start up in case it revved to the moon. Much to my surprise the engine idled right down to normal.
Next came the test drive. Under normal driving as described above, the engine was much more responsive. It suddenly felt like I thought the engine should have from the factory. In fact it felt as good now with the Mamo TB and a stock tune as it did with the Katech and a modified tune.
Next came the roll test, 1st gear rolling at an idle and stab the throttle, the stock TB was anemic to say the least with this test, nothing happens for a split second as the engine slowly gains rpm and eventually gets to a happy spot. The Katech was better in this regard and would actually spin the tires. The Mamo TB obliterated the tires almost instantly.
I tested each TB with a stock tune and a modified tune, but placed more emphasis on the stock tune.
The gains of both modified TBs could be felt through out the rpm range.
I'm the kind of guy that will purchase a product to try, if I like it, I keep it, if not I sell it at a loss and move on.
I'll be moving on to CAI and X pipes next, I'll contrast the Halltech and the AFE as well as the Borla and the Corsa.
I helped a friend install the Halltech on his car a couple of months ago. I was not impressed with the fit. But that's a different thread.
I will say his 2015 Z06-Z07-M7 has the Halltech, Mamo TB and does not throw any codes, he does track the car.
Of course the each of these mods is going increase airflow and lean the A/F ratio. It may be a case of CAI + TB + exhaust mods = too lean without a tune. In which case pick the combo that works for you or tune it.
For the money, I think the ported TB is a no brainer to start with as a first mod, next would be the X pipe for the sound and then perhaps the CAI or a better flowing filter if I can find a CAI that fits as good as OEM.
Hope this helps............

^^^^ I received and installed my ported throttle body from him this week as well. Even though I did not road test it I started it and it seemed as if the slight hesitation at initial throttle was gone. The blending on the throttle body looked flawless........For the doubters out there(and there are plenty of them) I had a ported throttle body on my 2013 ZL1 that I traded in on this car and the ported throttle body was a vast improvement on that car as well and you could really tell the difference at the low end.

I received it yesterday and installed it in the 2017 m7.
Since I was having absolutely no trouble with stalling/hesitation on low speed tip in I can't really say that is improved since it was O.K. to begin with. There may be a little more tolerance for a clutch/throttle application screwup starting from a standstill but it isn't a night and day difference. BTW I can also get the car gong from a standing start using only the clutch on level ground. My car idles at 600 rpm.
Since it was cold (49 F) I really couldn't really tell if performance improved since any application of full throttle in 1st or second at any speed resulted in immediate violent wheel spin. I did take it up to redline in third to try and check for any codes. There were no codes produced.
The workmanship in the throttle body is excellent. It eliminates the sharp edges and transition at the step which is cast/machined into the throttle body bore.
Since you can send it back if you find the additional functionality not worth the cost it's kind of a no lose proposition. I'll probably keep it unless some trouble, like throwing codes, appears when the weather warms up a bit.

I installed a Tony Mamo ported throttle body on my 2800 mile 2016 C7Z A8 the other day. It joined a Halltech CAI and Borla X-pipe as my only mods.
Here are my stream of consciousness thoughts:
1. Extremely well packaged for shipment.
2. Beautiful porting work done to a brand new GM TB (smooth, even, clean)
3. TB swap is a snap (literally 10 mins including getting the tools out)
4. Old TB had some liquid oil in it along with black residue.
5. Car started right away with no issues with new TB
6. The 15 minute backroad test drive was smooth as silk. I shifted through the gears with the paddles in manual mode to get the full effect of throttle modulation without any trans upshifts or kickdowns and it was BUTTER. I didn't notice a huge hesitation prior to the TB - but I can tell you it wasn't as clean and smooth a rev as I get now for sure.
I am a repeat customer of Tony's as I had a "Mamofied" Stealth MSD intake on my C6 Z06 and it was nothing short of a work of art and a true game changer for that car's performance. I can say that the level of quality effort he puts into his TB's is the same as his much more expensive ported intake offerings. This is quality stuff.

Picture 5-6 are my stock 2800 mile TB (notice oil on bottom of blade and black residue in housing)

Looks like he does great work on these. When I get my 2017 in the spring I will definitely buy one if it's confirmed that installing it won't throw codes.

For those worried about throwing codes.
Yesterday was a bit warmer, 55 with bright sun. Previously it was too cold to floor it in 2nd without violent wheel spin.
I took the car in sport mode from 50 mph through 2nd and 3rd to redline with no discernible wheel spin and into 4th without any codes being thrown before running up on traffic and having to lift.
I have a 2017 m7 with no other engine modifications. It would seem the ported throttle body by itself causes no code problems. I have no idea whether a CAI in conjunction would throw codes.
It seems to me that changing the shape/frontal area of the inlet pipe would tend to make the mass air flow sensor report lower then actual mass numbers. As I understand how those devices work they are calibrated with a specific cross sectional area and laminar air flow since the sensor itself does not sample all the air moving past the sensor.
