I just wondered how many have had the Cow Booster done to they're C6 and if they're glad they had it done and how much difference it made in the feel of they're Vette.

 

I had my 08 done about 9 months ago. The car was pretty much stock except corsa sport axle back and halltech CAI. The first time I "test drove" the car after the booster, I just giggled, then I asked Chuck to set the booster a little less aggressive with traction control and active handling on and to set it more aggressive with those features off. I was really worried my wife would pile the car up and she would never drive with the computer nannies off. It is MUCH more responsive. IMO, the way chevy should have set it up. Chuck also tuned the car. It made a HUGE difference (at least "seat of the pants" difference and since I don't track the car that is all that matters to me.)
If you search, you will find LOTS of similar opinions about the booster and Chuck's tunes.

 

I have had mine done and I am extremely happy. Mine is a a6, the shifts are much more firm. I had the Cow boost done, the throttle response is much more aggressive, it takes some getting use to it. He can adjust how aggressive you want the throttle response. He was at my house and many tunes each one that came back after he took them out to tweak in the tune had a big grin on there face. I would easily do it again.

 

My thoughts on a booster in our 09 A6 as I came from a near 800 RWHP C5. First is is for the street driving, that I do 99% of the time not the 1/4 his engine/auto tune is for this as well as. For the street.

When he first boosted mine I drove it solo and it was better but not what I wanted. So when we did our drivability he made it aggressive for me. I said better but more, so he not only went as aggressive as he goes he ramped the A6 tune a tad more aggressive for me.

Here is what I like with the booster and tune the most, booster for take offs from a stop at the red lights and slightly giving a throttle press it is instant response, like my old carb days. It makes initial acceleration response how I wanted. It took my wifey one time to approve of the change and she is into looking good in her Vett not racing.

The booster and tune go hand in hand especially for a stocker like ours, this winter I will see how it is with boost. How does the booster and tune work together on the street, I covered the take offs, when cruising around around 30ish and you hammer away I used to have two lags engine and A6 now neither. Depending on how hard I hit the go pedal the tranny will shift down 1 or 2 gears and while this happens the booster has got you throttle open now no delay.

I have a stock LS3 with the only mods are ZR1 exhaust and Airaid CAI, the cool thing now is the tire spin from my 325s that I could not do before on hard downshifts. Oh I have already learned how much throttle to do on downshifting to keep the tires from spinning, faster Vett this way.

Track the booster is not a factor and here is why, the throttle is already open and when the light turns green the pedal is to the metal. I load until the A6 wants to over come the brake.

Very glad this 99% non tracked Vett was boosted

 

Can he realy set it that way?

 

Yes he can, I had him do it the opposite way very aggressive

 

Wow i guess i will be calling chuck in the near future.

 

Also had the tune and booster done earlier this year. I agree with peter pan, response is greatly improved. This is on a basically stock 08 A6.

 

CoW Booster is rediculous.. It's the best $$$ I've put in my car so far... It's instant and obvious aggressive improvement to the response on the street.

 

Chuck tweaked my cammed C5,,,get ready here come the naysayers but Chuck knows what he is doing!

 

So does it actually feel like you have more power??

 

It's kinda like this .....


CoW 'Booster'

As you can see by the graph below, a mechanical throttle control using a cable system gives a linear throttle response .. When the throttle pedal is pressed 1/4 th of the way to the floor, the actual throttle blade in the throttle body will be open 25%. Press the throttle pedal down 3/4th of it’s available travel, and the throttle blade will be open 75%.

However, do to the programming of the “Fly by Wire” throttle system in the LS3, LS7 and LS9 Corvette engines, the throttle is not at all linear. Especially just off idle and in the first 65% of it’s range.

In fact, looking at the chart below, you can see that when the throttle pedal is pushed down 30% of it’s total travel, the actual throttle blade will only be open 10%. At 50% pedal travel, the throttle blade is open 35% of it’s total range. This is what gives poor throttle response during normal driving.

The CoW Booster does an amazing job of restoring the throttle response in the area of the lower throttle angles by operating the throttle system in a linear fashion as would a mechanical cable operated throttle.



NOTE: With the stock programming, operating in any of the optional driving modes such as “Competition Mode” will not have any effect in altering the actual throttle blade opening rate with respect to the throttle pedal position, so that is not an option that will better the situation. The “Booster” is still needed to provide a near linear throttle pedal to throttle plate relationship.

I like this addition on the wifes 05 and she really loves it
makes the car respond the way it should

 

I had mine done in February of this year (CoW booster and tune), and I have to agree with Peter Pan that the two go together especially if you have an A6.

My C6 A6 is stock other than a K&N intake, Bassani catback and tune.

The tune improves the A6 shifting and the booster removes the throttle delay. Prior to the tune and booster, I always drove in S mode but after the tune and booster, I drive mostly in D mode as the shifting and feel of the car is vastly improved.

My C6 is my DD and the booster did take a little going used to but the changes are well worth it.

I realize some will ask about HP gains, but for me that was not what I was after. I become frustrated with how the car drove (A6 shifts and throttle lag). I wanted a car which drove "better" for me and that has been accomplished. Yes - "better" is subjective, that is why Chuck will change things up specifically for you.

 

I too had the Tune and Booster done this past April. All I can say is WOW!!!!!!!!!!! Best mod to date. Car runs much better and the delay is a thing of the past... I agree with everyone here who had it done. The only thing I will add is that it makes the car feel much lighter than it did before....

Thanks fellas!


YES, CoW BOOSTER is AWESOME! Wether you set it MILD or WILD or anywhere in the middle.

We can also set it up so that you can change between 2 different CoW BOOSTER profiles using the TC ON/OFF button

without changing the way the TC works.

REMEMBER: Your LSx engine makes SOOO MUCH POWER DOWN LOW AND OFF IDLE

that GM had to "take away" throttle opening (which clips power significantly) down low just to make the

drivable for EVERYONE.

While I CAN give you back ALL OF THE POWER, my experience shows that it's undriveable and not the slightest bit fun.

I've spent years working on a few different maps and polishing the curve to make it as powerful as possible

without over doing it.

The maps I deliver on the first flash are usually comfortable for most people and yet a MASSIVE IMPROVMENT

in low and mid range TORQUE and HORSEPOWER.

CoW BOOSTER!

Hi Chuck...feel free to pm me if that works better for you but some people like the responese here too.

I have a '07 manual vert...with just an exhast upgrade and air intake. Most of my other mods are cosmetic. What would be the benefits to me doing this? Also...I am very interested but live in London, Ontario....and likely won't be near one of your tune locations any time soon. I think you can do this remotely...what is involved from a time standpoint or mechanical skills?

Thanks

 

I cant wait to get this.

 

Remember it does take some time to adjust to it. Do not drive it at first in bumper to bumper traffic. It will give you smile per hour.

 

The Benefits? HUGE throttle response and power very early in the throttle opening and thru the mid range.

For Canadian customers, I'll usually take your order and ship you one of my pcms with the booster installed.

After you drive it a few days and you're happy with it, you send me your pcm as a core and you keep mine.

It's very easy to do like that.
