man..I just found out i have one in my Z and I know the car is running pig rich. Anyone running one? How much timing and FP does it bump you up? Is it only at WOT or all the time...thanx

I have one and I like it alot, I think it's all good, of course it runs rich at WOT, according to air/fuel guage(haven't checked with a scan tool yet), but there are still bars left for it to run richer so. I don't know, Nice rev limiter at 5500 rpm. picked up ~.5 sec and 3mph with the chip. BTW it can't adjust your fuel pressure. I couldn't get much specifics out of SLP about it, I noticed on the highway it doesn't seem to go into a "highway" mode like the stock chip used to just go lean and stay there on the highway cruising, where now it's always rich/lean/rich/lean, like normal operation at part thorttle. My gas milage has remained about the same as far as I can tell. Do you have any other mods to your car? I believe the SLP chip was designed/tuned for a car with SLP headers, cat-back and SLP runners, CAI, and cooler 'stat, I'm not positive on that one though, but I don't think it was meant for a completely "factory stock" engine. Nevermind I see your mods in sig. What's it run?

14.62@96mph headers, muffler, chip, ghetto stuff, duct tape
89 GTA 305 TPI 5 speed 3.42 gears

yeah..mods are in the sig. I'm working on getting the headers ordered ASAP. I hate these gay looking manifolds. The best it ran is a 14.28 @ 98.86 (slip isn't in front of me) The 60' sux sooo bad I'll I do is spin w/ a 2.1X-2.2X 60'
