Getting a "performance" chip replaces what? The eprom? Anyone know where I can get the stock one?

This guy I am buying a maro from doesn't know exactly what was done to the car. He said it didn't pass emissions (he tried once then moved a couple counties south so didnt have to get it tested anymore). He says he 'thinks' it has cats (I will be looking tomorrow night) but it also has a chip which I imagine could cause it to run rather rich.

Any info you guys can give me would be great. He doesn't have the failed Echeck papers from 3 years ago. I am just theorizing -- checking the cats will tell me more. In my experience a generic performance chip on a gasser doesn't do a whole hell of a lot. Thanks a bunch! (there is a pic of the car heren the forums here : https://camaroforums.com/forum/intro...22/#post548320 if anyone is interested.)

EDIT** Also a little about the car (what I know at least) : Headers, at least a cat back, intake and something involving MSD (don't know what exactly, have been looking at stock maros so I know what is out of place on this one) in addition to the chip. Don't know brands, I would like to but he doesn't have a clue and he is a "take it to the mechanic" type guy which means he hasn't touched the car much. It's a 94 z28 m6

 

Didn't read post. Pull the chip out, they may your car run really lean!

 

take some pictures of the msd part and motor so we can see. best to use a tuner like solomon LT1 PCM Tuning - OBDI/OBDII PCM Tuning/Programming Service or pcmforless PCMforless.com .

 

Thanks for the replies

I am going to go look at it tonight I will be sure to take some pictures
