throttle response

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.

The Best of Corvette for Corvette Enthusiasts
Take the car to 3K in third gear, come off the throttle fully, and you will see the lag before the RPMs start to drop down.
Did you ever own (or drive) any muscle cars from the 60s-70s with steel linkage between your foot and the carb? If you did, then you would notice the lag on the C6. Not so much under normal driving, but dumping it from a standing or rolling start it is quite noticeable.



















oh sorry Dave!
