Do performance chips work if so could somone tell me what some good ones are? Thx

 

The short answer is no. The long answer is no.

Youhave to reprogram the PCM. If you have a laptop, there are a couple of programs but their names have slipped my mind for the moment. The chips are just complete rip offs, evade them.

I had mine retuned at Carolina Auto Masters in Durham, NC by a guy with the progrma who used the dyno to tune the car.

 

no but programmers do...use the search feature, doesnt work the greatest but it will make everyones life easier

 

There is a middle of the road answer, also. NO

 

A performance PCM is what you would want, only worth it if you have a L67 though.

 

or major mods...and not just a cai and some new mufflers

 

Justa note to everyone.

I wouldn't trust the site's search feature to find my socks or much of anything else. I've tried to use it to find a thread I knew existed (I created it a week earlier), and it couldn't find it.
