Re: check out my turbo atap log, race tomorrow. Too bad you can't resize that pic it's screwing up the frame...
Looks like you go pretty lean from that point onward.
I plan to run my upcoming blower project at 11.2-11.5:1 AF on the dyno... probably like 950-1000 02's at WOT.

Re: check out my turbo atap log, race tomorrow. thats code straight from atap.
running richer than 950 makes my car stumble bad.
i know its lean, what i cant figure is why.. like i lost fuel pressure or an injector stuck or something? or (based on the knock) was it actually fine and a-tap just got a bug there?
