Question about 98...computer related

mail order chips are a poor idea. You need to actually go to a reputable facility and get the car wide-band tuned and monitor the a/f ratio. This way they can make pulls on a dyno (or, prferably on the road), reburn the chip, slap it back in the pcm and try it again. It will most liekly take several burns to get it right for your fuel octane choice.

Houston Performance is an authorized Autologic chip tuner. I don't have the number handy, but the owner is Steve Drier.
