Hypertech Chip
 

Has anyone had any experience with a hypertech chip. My car is a 90 LX convert w/ AOD mostly stock, exhaust and cold air. The chip seemed to help part throttle but seemed very rich. I check fuel and sure enough was at 43. Put on kirban adj. reg and set pressure at 39. Much better but lost top end and pings slightly ( timing only at ten) and still rich at idle. Am I better off without chip and set timing back to 14 now that fuel pressure is correct. Any ideas?

Personally I do not like what Hypertech does. I have not had good luck with them at all. I have had good experiences with the Superchips Brand chip. The one's out of Floridia. Just my personal opinion.

well it's always better to get dyno time with a chip tuner than to just order one over the phone. I would probably give them a call and see what they will do about reburning your chip to match your mods and changes your have made.

If it's not too much of a problem pull the chip out and see how your car reacts then.
