Yeah I noticed my LTFT in the 5000-7400 RPM range changed from +1.56 --> -1.56 in between those runs. That would explain why the first run was slightly rich and the second was slightly lean. Most likely my LTFT's are still adjusting. FWIW on the previous tune, LTFT settled around +2 to +3 in that range (and slightly rich).

Ambient temps were 70-75 F. Intake temps were 95-100 F.

BUT I WANT THAT HPDE TROPHY! Hahaha. Yeah I'm thinking the same thing as you, I'll let LTFT's settle and see how things look before June 11-12.

I will say, I'm getting less of that fuel smell around town so that's nice. I wonder if any changes were made to MAF scaling or if this tune just runs leaner for some reason.
