Oh this could turn out hilarious, a mass Red "X"ed Grand Prix tail light, awesome :lol:

 

 

Oh yeah, another suggestion to try is Sinister Performance, *GM Tuners* He did the chip in my '90 TGP/4T60 and for only the 2nd edition, it does a killer job.

I hate to get back on topic.... :lol:

 

What exactly do the chips do? Like I've read the site and everything, but real-world in-car installs.... How much of a performance increase do you guys have?
