Nice pics! It was nice meeting all of you who I haven't met before. I had a great time watching all you guys put down some impressive numbers!

When I left there i went down the road and got some 100 oct gas. took $50 worth. I let it work in and i did a WOT run last night around 12:30am and I saw no KR until i was deaccelerating which could be exhaust rattle or just a need for new motor mounts. my ign timining is alittle wierd. it drops to 0 towards the end of the scan. i should have used the 100 oct for the dyno run. i would have seen better #'s. Boost goes pretty high, 11.73 psi. here is the scan:

I have just the small stuff done. i thought i would have seen more than that but i couldn't get a wideband done cuz of an exhaust leak.Mods: 9" k&n open cone intake, 3.4" MPS, DHP PCM v1.0, ICCU race verison, 180 tstat, 3" exhaust, u-bend delete, res delete, maganflow mufflers.

It looks funny b/c you have a drop of timing for a couple cycles. I was going to say that the KR at the end could be explained by looking at the O2s. the throttle snapping closed when you let off creates a rich condition (i.e. no more air coming in). The PCM detects the throttle is closed and goes back into closed loop mode. Because of the rich condition sensed by PCM (last O2 reading was > .450) it shuts off fuel, which if you were still flowing at high RPMs then you could create a lean condition.

But you're still flowing a lot of air (MAFF > 9000) and boost is high which tells me the throttle was still open. So there was some sort of glitch. Maybe false KR. But that doesn't explain why it looks like the O2s were back in closed loop.

Maybe a injector funny? could cause a small drop in O2s.

What part of the scan are we talking about. At the end, the timing and O2 drop because he's no longer at WOT.

i don't know what happen there but the car runs tons better with the 100. i need to get the timing tables put in my PCM so i can further adjust it to the cars needs. i will be getting a laptop soon so does anyone have any HPtuner or DHP PowerTuner software(would that work) that i could load on it and also does anyone have the timing tables too. Thanks

OMG, qwick, some one post the link to the DHP log color or whatever.
