I think I'm done tweaking my tune, finally I have had the same tune for the last three trips to the track and I am sure now I have the A/F where I want it for my current setup. I'll be still watching it like a hawk but I don't think I want it any thinner. Not sure how much power I gained going from 11.5-11.7 to 11.9-12.0, but no more traces of black residue in my tail pipes and I don't smell the gas on the cats as much after a run. I took my time coming at it from the rich side, but I felt more comfortable doing small changes and several runs inbetween tweaks and keeping it richer for the break in. It runs strong with spark still at 24* without any knocks using 93 and a bottle of off-road booster. Now if I could tune my driving to exactly where I want it, not likely. This is the LM1 log from 2nd and 3rd gear from my last run Sunday, I don't run 4th out so balls to the wall third gear is better to see the entire RPM range. So what do you guys think for pullied, unported with HE upgrades, NO big blower, NO juice (for now)... my A/F is where it needs to be right???
