ok from my 1-2 shift when i floor it my exhausts lets out a spitting kind of backfire sound well 2day i did it watched my RPMs looks like i banged the rev limiter 2wice in D and once in OD from about a 15 mph roll...how can i get this fixed? cuz it spits then shifts...feels a strong kick tho when 2nd gear grabs....what do i need to have done?

 

Some simple programming. Maybe there's somebody
near you with HPTuners for an '02 F-body. Several
other things you can do about shifting (like part-
throttle kickdown) to make the car drive better,
while you're at it.
