Can try installing a Sprint Booster. It does not enhance the performance limits of the car, but will definitely enhance the throttle response. I am using a similar device, Velocity, and I find the enhancement is really good 
A cheap and effective way; only thing is, if set to max (there are 4 levels of setting for mine), the car will really go WILD
.... sure to wheel spin on start if not careful.
Can try if you don't intend to enhance performance limits, but just wish to enhance the throttle response. Check out the reviews on Youtube.
