As a long time respected member and contributor to the forum, and a guy that puts serious miles on his Vette, you should try it. He won't charge you if you don't like it. Knowing you, and having a lot of respect for you, I think you will love it.
Joe, I like the "feel" of my car already. With a 3600 stall, it's a whole lot different than your M6 or my OEM converter. My wife can drive it just fine, because it doesn't need a delicate touch. If you ever tried driving with high heels on, you'd understand those problems.

I'm still working on the A6 launch device that I mentioned before. It shows great promise, but only if I can find a good method to accurately adjust it for different tracks conditions. Testing is limited to the parking lot presently, since the track won't open for business until at least mid-October.

There is no doubt that GM engineers devised the C6 throttle map for those in high heels indeed! I said that the day I bought mine. Matter of fact during the test drive. My c5 had much snappier throttle response. In fact, though I don't drive in high heels, I had Chuck throttle my Booster back a little as it was too touch in the first iteration. He literally called it the high heel version!

I always look forward to your mods and engineering ideas my friend. I'll stay tuned, and I was happy to hear your track is re-opening.

The Booster is more linear so the pedal is more responsive. Stock maps give you less throttle for a given % of pedal, and it "catches up" to 100% open much later in the pedal travel. So the first 50% is lazy, the last 50% is doubly fast. The numbers aren't exact but you get the idea.

The linear feel of the pedal makes a huge deal for us manual trans guys. Probably less of an issue for you automatic guys I'd guess. With a manual you need instantaneous response to a tickle of the pedal to properly heel and toe, if you need to floor the pedal to get a response, you're not going to be able to do it unless you have a double jointed ankle.
Joe, I understand perfectly how it works. I see the scans and know exactly how far the pedal moves and exactly how far the throttle plate opens and the TB motor acceleration and deceleration ramps and even the amount of time required to change throttle plate movement from one spot to the next. But when Chuck says I can't press the pedal to a location on any car to duplicate the same power result as it would with a booster, that's just a totally flat wrong statement.

If it takes 80 HP to accelerate a 3000# car to 60 mph in 20 seconds, remapping the pedal to TB plate opening rate will not change any of those factors. It may change the distance of pedal movement, but the amount of power required and the throttle plate opening will remain constant. Of course, that all goes out the window if Chuck has discovered a previously unknown branch of physics.

That's totally spot-on. Really couldn't have said it better myself.

Now, that said.... Lots of higher end cars now have different throttle mapping options from the factory. My M3 had 3 different modes, and while fun to play with, don't make the car any faster or really eliminate to inherent lag that electronic throttle systems have. The Cow Booster doesn't reduce this lag -- it just makes the pedal mapping more linear. I seemed to like the more aggressive throttle maps best in my M3, but that car didn't have 700 rwhp either.

I don't think I'd be bothered by COW's advertising campaign if he represented it as what it really is (and didn't throw in random !!!!'s and CAPS everywhere). HP Tuners really can't make throttle map changes, so I think he has a good product. Don't think I could ever give him any of my money, though.

I'll say it just ONE MORE TIME. YOU (meaning everyone) CAN NOT REPLICATE what CoW BOOSTER! does with your foot.

Many people have suggested this to me, but after they try CoW BOOSTER! they realize that it's impossible to do what they

THOUGHT they could do with their foot.

You're certainly welcome to come here and have it proved to you in person...or you can send me your pcm and I'll

do it for you thru the mail......

Or you could just (like others) decline my very generous offer and continue to misunderstand it and make comments about things

you don't understand.....

"It may change the distance of pedal movement, but the amount of power required and the throttle plate opening will remain constant"

What!?!??! Let me help you out here again.

The throttle opening is LIMITED FROM THE FACTORY.... I HAVE MADE IT SO THAT THE THROTTLE CAN BE "MORE OPEN" than it was previously relative to pedal.

SO, in conclusion..... I have allowed the blade to be "MORE OPEN" at a given point and so, MORE AIR COMES IN...AND MORE POWER IS MADE at given point.

It boggles my mind to look back at the thousand plus times I spelled it out soooo clearly and to this date I still have guys like you make these erroneous statements.

Trouble is, what you think makes perfect sense TO YOU is wrong and since you don't understand the concept, you rant that I've invented some new physics...

Sorry Pal, It's the same ole physics that we're all stuck with.

Either you just don't get it, or you're just here to harass me for fun....

Sorry pal, but you're the one who doesn't understand what I'm saying. Then again, maybe you do and it forces you to respond by twisting the facts and taking parts out of context in an attempt to discredit the message and demean me. Hmmm, which one is it?

I don't have an issue with the product itself. It's just not one that's suitable for my needs. I can't speak for the needs of the OP, but he obviously has some concerns, since he's asking for solutions. Without identifying the problem completely, offering a product you sell as a cure, is as unethical as a doctor recommending brain surgery every time someone complains about headaches.

You can present your product as some totally new concept to people who truly don't understand what's happening and they'll believe whatever you tell them. AKA the P.T. Barnum principle.
Or you could present your product for what it is, without all the "I'm so much smarter than everyone else" attitude and the "You have to try it to know it" Nancy Pelosi principle.
But when you present it with factual errors and half-truths, you can be assured that someone here will point it out for the benefit of those who are less informed. If you consider that harassment, then so be it, because it'll be self-inflicted.

You say that it's not suitable for you. That's fine. But why then do we have to have you comment soooo frequently with

opposing comments you make? Given that you don't understand all of the principals at work here why must

you continue to involve yourself in these discussions???

For those that are not interested in what I do, couldn't you be the one that reads and keeps his

inappropriate comments to himself???

Actually, I would prefer that if you're questioning my TONE or CAPITALIZATION you should understand

that I consider your continuous banter about what you do not understand.....Quite frustrating.

Why don't you just NOT involve yourself at all if you're not interested???

That would be nice.

I personally don't like to run tunes that have knock sensors function removed, dial in excessive timing, elevated oem engine cut outs and such to have my engine to run like a "Rap ape" and risk blowing up my engine as some have experienced in the forum here in the recent past.

What you have done is create different throttle map profiles -- much like what comes in almost every newer BMW at the touch of a button. IT DOES NOT CREATE MORE POWER. And what HOXXOH is saying is correct. If you want 20% throttle opening, you can have it with or without the modified mapping. It just requires a different accelerator pedal position.

It isn't a complicated concept for someone familiar with modern engine electronics and performance tuning to understand, nor is it a new concept on performance cars. I think it is a good product in that HP Tuners and the other major LSx tuning software can't make these changes. I just wish you'd represent it as what it is -- which isn't anything to be ashamed of.

Is not correct. I've said it 1,000 times. I'll say it again...and again.

CoW BOOSTER! WILL NOT increase you peak (WOT) dyno number..... WILL NOT.

Let's stop using the term "CREATE MORE POWER". I don't say it that way ever and don't represent that.

It WILL ABSOLUTELY GIVE YOU MUCH MORE POWER in the lower RPMs and PEDAL POSITIONS.

It DOES NOT create it by magic. It simply ALLOWS THE THROTTLE TO BE "MORE OPEN" relative to pedal than

ever possible. When the throttle is open more...More power is made. SIMPLE.

If you want 20% throttle opening, you can have it with or without the modified mapping. It just requires a different accelerator pedal position.
Again... Not really. I'm not making this difficult, but I AM trying to make a point here.

The only people that really GET IT, are those that have driven CoW BOOSTER!

Having not tried it, people think that they can "just press more" to duplicate what CoW BOOSTER! does....And they CAN NOT.

The reason I get into these discussions is because I resent people passing judgment on something they "THINK" they understand....When they don't.

Most of this argument is due to the fact that most don't understand that there is a dimension to this that is not readily apparent

until you try it. That is, that a human is not capable of controlling the pedal to get the same effect as what I do....

I install between 2 and 10 CoW BOOSTERS! per day between local customers and mail order stuff and as it wold appear.... everyone

loves it. The ETC system in these vehicles is far more complicated than anyone knows and unfortunately there are those that pass

judgment with no experience and no knowledge beyond what tables I've posted here.

As frustrating as these threads can get to maintain, they generate lots of interest and orders despite the 2 or 3 people that will never stop ranting.

I actually think, the more that I explain myself in these posts, the more popular the product becomes and the more confidence readers have.

Interestingly enough, a couple of hecklers think they're pissing on my product, however every time these threads pop up

E-mails come in and my phone rings....

Go figure.
