Are the performance chips offered for the 3.1 v6 worth the money. I have a 93 pontiac sunbird convertible and plan on doing the cold air intake mod, throttle body by-pass mod and some exhaust work. I was going to buy a chip but wanted to know if anyone has seen any significant changes in their car by putting one in. E-mail me or post a reply. Thanks, the sun is great when the top is down!!!!!!!!!!
