Does anyone have any before and after numbers from chucks tune and cow booster?

 

12.41 @ 117.50 PB bone stock
12.14 @ 119.16 PB local tuner with CAI
12.24 @ 117.44 PB CoW tune with CAI
11.99 @ 119.12 PB CoW tune with CAI and Z06 exhaust and DR's
11.89 @ 122.12 PB local tuner with CAI and Z06 exhaust and DR's

After that, I've changed several things and tweaked the tune myself. My current PB is 10.80 @ 126.84

I don't have the booster, since it's a detriment when drag racing an automatic.

 

Why is the booster a detriment? Just wondering...?

 

Interesting. I guess the local tune shows different results because it specific to the personality of your car and CoW tune is generic for your modes, correct?

 

my thoughts were local dyno tune vs mail order tune. if so, that's not too bad.

 

I believe LS1LT1 tried a Sprint Booster at the track and saw zero gains. I know it's not the same as the CoW Booster but they have a similar goal of increasing throttle response. I believe Mr. LS1LT1 actually did not like it for the track because he almost red-lit when staging. I'm sure that's something that can be learned around but it still showed no improvements in his ETs or MPHs. Perhaps the CoW Booster would fair better but I always figured these types of mods to be more for daily driving street car fun.

 

I love the CoW booster. I think its the best mod I have to date right next to my a4 tranny tune.

 

ROCK ON MY FRIEND!!!

So very glad you like it!

May the BOOSTER! BE WITH YOU!

Since it opens the throttle plate at a greater rate in relation to the foot pedal movement, it's harder to have the control to squeeze the throttle. Sorta like a radio volume **** that goes from quiet to nearly full blast by the halfway point of rotation. The throttle plate opens to a greater amount too quickly for a smooth launch.

 

The local tune was done on a dyno and followed up with a street session to fine tune it. The CoW tune was done on the street only and more attention seemed to be placed on the transmission than the engine. Yes, the CoW tune felt better SOTP, primarily due to the harder hit of the shifts, but didn't perform better in the real world. In heavy stop 'n go rush hour traffic, I was forced to paddle shift and hold 2nd gear to avoid the lurching on the 1-2 shift and hitting the car in front of me.

If all you want is the SOTP feeling of power, then the CoW tune may be good for you. If you want more real power to beat someone at a stoplight or deserted road, then get a dyno tune. A .10 second difference in a 1/4 mile race is equal to 17.6 feet or 1.2 car lengths at 120 MPH.

 

If your foot is 100% to the floor.... Both, products do nothing.

EVERYTHING under 100% throttle wakes up GREAT.

My CoW BOOSTER! can be adjusted to ANY level of sensitivity.

The BIG trouble with the competitors product is that the throttle is 100% open any time your foot

is about 3/4 down on the pedal. Scary to think that the throttle is 100% open for 3/4 of pedal travel.

I think the pedal should ONLY be 100% for the last few % of the pedal travel....

It sounds a lot safer that way and the "resolution of the throttle is much better with mine.

CoW BOOSTER!

I understand how the cow booster works, I am just trying to justify the price of the hand held the tune and the cow booster and leaving a little power on the table from being a mail order tune (no fault from chuck) vs a local dyno tune.

 

Any good tuner leaves a little power on the table.

Regarding how MY tuning works, You have to realize that some years back,

the wideband equiptment we use was just being developed for the retail market and in addition to that

the way in which it was connected to our tuning software was under development at the same time.

For the guys doing it as long as me, you may remember many guys did not have access to widebands

and widebands were not easily configurable to our tuning software...if at all.

Also, mail order tuning was VERY different. It was load a tune...send out a pcm for a swap.....and be damn sure it runs

right and does not come back. ONE SHOT DEAL.

No AutoCal, no DATALOGGING, NO REMOTE SERIAL WIDEBAND, and most of all NO SECOND TRY.

Like everyone in this business, all tuners in this business started "somewhere" and wideband development started "somewhere"

and we sent out pcms that ran great, but were a bit conservative on the big end as there was no second chance to datalog or

e-mail a new tune. What you sent out had to work, make the customer happy, and last.

FAST FORWARD TO TODAY: We now have AutoCal with my SERIAL WIDEBAND, thousands of tunes out there running hard,

plenty of feedback, plenty of experience, and the best tools in the business.

Just like everything in this world evolves.... So does the mail order tuning process.

Right now is the BEST time to jump on a mail order tune if you ever had reservations.

The price should be easy to justify when you a) GET MY CoW BOOSTER! and b) when you talk to some of my mail order

customers and you see how much time I actually commit to the process.

My stuff is not a copy/paste "see ya later" product.

I'm investing LOTS of time with the work and with support for customers that need it. Sometimes overwhelming for me.

When you was the BEST in mail order tuning, You want my TUNE, AutoCal/CoW BOOSTER! package.

No, it's not a $149. mail tune.... We don't do that here.

Ok quick question Mr. Cow, What if one was to purchase the cow booster first. Then added a supercharger kit but the car was tuned by the installer. Would the booster interfere with the next guy's tune or does it not have anything to do with it? Also, how does it work? Do I send the ECU out to get boosted?

 

Does not matter who tunes it, but it's better if the CoW BOOSTER! is installed first.

The booster has NOTHING to do with any of the tune and there are no tables that overlap or need to be touched.

If you already have a tune that you really like, then send me the pcm.

If it's presently stock, you can send me the vin # and I'll ship you a pcm with the booster and you just send me back your

core pcm.


I can make it SUPER EASY no matter which way you decide to go.

Call me any time to discuss. 914-332-0049

Thank you for clarifying that! Yes at the moment my car is 100% stock and I just bought it a few weeks ago but was only able to drive it 2x before we got blasted with all this snow. They gave me a copy of the carfax (clean) and all the maintenance records that were with the vehicle from the previous owner. Appearently, a little over a year ago, the owner had an issue where the vehicle would not start. It had always taken to the dealership for maintenance so he took it back there and they figured it out as a PCM issue and replaced it for him under warranty so my PCM is basically brand new. I'd rather just mail mine out to you. Personally I don't care who tunes it as long as it gets done right. From what I've read 100x before, most guys here (That have your tune) are totally satisfied while others tend to naysay it because they haven't got one.....yet. How much for just the Cow Booster with shipping to 03053? Are you running any specials soon?
