Well back on topic.... JayDeeEmDC4 find a tuner local to you to program your ECU and TUNE your car. Go to www.pgmfi.org and check out their scene. They use Crome software which is the best imo.

Otherwise, stay away from eBay chips and other generic programs. Even if the eBay chips were any good, which most of them are garbage, remember that they are just "base maps".

A base map is not a tune... no car is exactly the same.

Even if it is the same year, same car and with identical mods... add to that the differing mileages on your engines and the fact every state has different gasoline formulations that change seasonally. Your car may feel better from one of these chips, but even when feeling good, the engine could be running dangerously lean at points.

You all spend so much time and money on your projects, don't go cheap on the tune. I see this all of the time, everyone is happy spending the big bucks on the mods that are visible and easily shown off to their friends and rivals. Then it comes time to get their car tuned properly and they try to cheapen out. I saw this two weeks ago in MA. Stupid kid has no problems spending his money on repainting his rock chips for the auto shows, but wanted to nickle and dime on the tune for his newly boosted engine. Dumbass.
