i have a 95 3.4 and i was looking around and came accross the Jet Performance chip modules. stage 1 and 2. i was wondering if anybody has had any experience with these or know anything about them....good or bad idea? worth it or not?

I have also looked at those for a 94. The stage 2 is for high flow cats and low temp thermastats. The stage 1 is for slightly modified cars. You also need to make sure to get the right one for you transmission, auto or manual.

Usedboth Jet chips on 3.1 Grand Prix, and did not seem to makea noticeable difference. I suspect they will act the same on a 3.4.

Did you tune those to your car at all? I do believe they are tuneable.

You are very limited to the amont of tuning that can be done with them.

They are a waste of money.
