Tuning is a MUST.

This thing is very fast, I can tell just at low RPMs and low throttle. I say low RPM's and low throttle, but that includes quickly getting it to 100 without even trying. But as soon as I'm WOT or close to it, I get backfiring and detonation. During last nights test drive, the detonation would be followed by a sort of "safe mode" until I stopped and restarted the engine, and gave me CEL and codes for a few cylinders misfiring. I should have filled my methanol tank before the test drive, but I had just planned on waiting until I tune to worry about that. For now I just need to get this Apexi working... the RPM signal isn't working anymore for whatever reason. I'll do some rewiring and keep you posted.
