I am a new owner of a 95 GT with auto trans, I like
the car and just replaced the stock alternator (was bad) same time cold air intake kit. lookng for
pro's/con's, good/bad advice on buying a performance chip off ebay or elsewhere for my car?
 

Performance chips are ok but not really going to help you car out a whole lot. Unlike new cars the chips only changs minimal things. The new stuff is more programmable do to it having PROM and not just ROM. to get any noticable power you need to do more than just a programmer
