 Almost Full Throttle 3rd gear pull - Dizzy tune testingCostco91 gas, a bit cooler ambient temps I think 14c, cylinder 3 has some knock, didn't reduce engine timing though.
boost pressure dies off at higher RPM as charge air temps rise.
I could have sworn I was full throttle before 2500RPM and it looked like I went to 7,000RPM on tach, but log indicates otherwise.

AFR high? 94 Octane with Ethanol, tank was running a bit low, not sure if that was a factor.
Just switched from a well performing (I think) Cobb OTS 91 octane tune to the 93 octane Cobb OTS tune,
I noticed it doesn't seem to allow as high boost pressure, timing isn't as advanced either, and seems to have higher AFR #s when on the throttle. Could be due to temperature / air differences or the fact that the Accessport was still learning to trust the Octane when re-loaded the new tune. So further experimenting is probably needed.
When I first loaded the tune Octane Learn was at -0.75 (ideal is -1) as I drove it slowly fell to negative -.80, -.85 etc until it hit -1 . This log was likely done at -1 or very close to it.
