Throttle lag
I came across this on the nhtsa.gov site. I guess this was in response to complaints from car owners about throttle lag.

I noticed this right away with my car and it's a 2004.5, but I thought it was due to the supercharger. Since I never had a car with forced induction/boosted car (my MX-6 was NA), I didn't know whether there was a lag with superchargers just as there was with turbos. I found out quickly after, that it's not necessarily the same situation (even though both superchargers and turbos provide power through forced induction).
Not sure if there is any programming that can be bi-passed through Star Diagnose to take off the speed control, but it's something that I've not liked on the car ever since I got it (which is really rare because I Love most things on my car).
If anybody can shed some light on this, that'd be great!

What aftermarket chip tuner would you recommend?
