No Chuck your Cow booster is not the clear winner on this forum. More forum C6 owners use the Vitesse. The Vitesse is also adjustable on the fly. It is also plug and play. No need to ship your pcm or purchase an Autocal. Vitesse Is The Clear Winner!
My CoW BOOSTER! is the only 100% safe and proven product...
There are no wires to run and it's impossible to mess up.
More flexible to program and when compared back to back with others...
Our CoW BOOSTER! is always the hands down winner.
Call any time!

Facebook has this cool feature that when you BLOCK someone, you don't have to see their absurd posts when you browse.
I wish this forum had a feature like that.

No chance of "Bricking" the PCM , no chance of a bad flash ...
And for those that chose not to spend the $900 for the Auto Cal , pulling the PCM shipping it to Chuck and then reinstalling also is much safer than unplugging one connection on your gas pedal ....Right........
Which by the way if anything goes wrong with the Vitesse you just get a reduced power message ... of course reports are few and far betweeen and ussually are a result of a bad intial calibration , worse case just unplug it ......
You never see Vitesse bashing any of the other competitors ... a true sign of a professional business man
There is room for both products ....and both are great solutions but in the end its up to the customer to decide .

My 2011 Toyota pickup acts perfectly normal, I have no idea if it's drive-by-wire or not.
I drove my neighbor's Subaru last night and that was just the opposite (it's probably a '14 or '15). On taking off from a stop the pedal was very sensitive, and I mentioned to her that I wasn't used to it. She said it takes time. By the end of the trip I got better.
Amazing, with all the "latest tech" you can't just jump into a car and drive it. You have to learn "it." It was a drizzly night and we never did get the heating system figured out. Too complicated plus all the stupid symbols for the illiterate people out there who shouldn't be driving cars anyway.
I mentioned to her it was so much easier in the old days where all you had was a lever for "Heat" and "Defrost," and you could balance it anywhere in between. Then another lever for temperature, one end said "Cold" the other end said "Hot."

For you guys with the manual transmission...... does the Vitesse controller make rpm/speed matching more 'touchy' when going through the gears? I'm tempted to try it but unsure how it might affect driveability (smooth shifts).

I have no issues going through the gears of my 6 speed with the Vitesse.

No issues with RPM matching at all on mine. Nice and smooth all the way through.

Just bought a z06 a few weeks ago. This car is like nothing I've ever owned as far as power and sportiness. Took me a bit to get used to the car. After I acclimated somewhat, I noticed pretty quickly how laggy the throttle was. Piles of power once it started moving but far from crisp. Started researching it and immediately came across this Vitesse controller. Put it on and started trying different settings. 3 is noticeable. 5-6 feels like my foot is directly connected to the engine. Over that is almost too twitchy for me. Noticed that any bucking in the car gets amplified quickly until i can get my foot off the peddle. Like a pothole in the road building. I'm betting it's quite a simple device but 100% the best and fastest mod you can make. Do it if you haven't. Makes it hit like a train.

throttle response lag
Do you know of an aftermarket tuning device that will do the remapping? Or is this something a good dyno tune shop can do?
The lag, both on and off the throttle is very annoying. Might be OK in Grandma's car but doesn't belong in a Vette.

Hate to burst your bubble, but your still going to have lag even with the controller.
Hence GM programmed in throttle response lag, both pushing the throttle down, and letting off on it as well.
This was done to help gas mileage, as if you where holding the pedal steady instead.
Granted that your going to get into the meat of the power with less pedal push with the Vittesse controller, your still going to have that slight delay on pedal push before engine responce, and the same delay coming off the throttle before the RPM's start to drop.
Note, if you push the clutch in, it will allow the RPMs to drop instantly instead.
In the z06 throttle mapping, GM did not program as much delay into both sides, but its still there to a lesser degree instead (why you can't buck the car with the gas pedal like you could on a carb car).
Bluntly, if you are wanting crisp like a throttled carb car, then it will take a remapping of the throttle response tables in the ECM instead (which HP tuner and EFI live can not get at to do such). Also, you have to think of terms of spinning mass, such as the flywheel and clutch that lighting them would help to allow faster RPM climb and drops as well.
To sum it up, with the C6, you really have to think ahead when driving, to deal with the delays of the two and how you drive the car.

Could you describe to be that lag you experienced to me??
Sometimes i notice no throttle in the first tip in (maybe 15% throttle), sort of dead space. But somtimes the throttle is right there at the begining of pedal travel right away just like my other cars.
Are you experiencing this same deadspace?
Because otherwise I think i may have a different lag than what everyone is describing. Dont get me wrong about the performance; i have a tune that has an increased "pedal-to-throttlebody" quick ratio plus a ported throttle body plus 3.42 rear end plus z51 short ratio transmission plus small dia. long tube headers...It has very sharp throttle response BUT there is a LAG in the first 15% tip-in of gas pedal (but only sometimes).
