I finally ran some logs on the BD regular tune with +2 timing and compared them to the BD premium logs. At the track, my Titan ran faster each time running the reg+2 tune than the premium tune on two different trips. That includes running the premium tune with +2 timing and 0 and -2 timing. I only logged RPM, timing and AFR volts banks 1 and 2. My software is slower than Uprevs, so I recorded both AFR banks on 4 separate lines to get more readings.
What I found was each BD+2 timing tune (reg and premium) ran fairly identical. That being the timing ran up to 35-36 degress at about 5500 RPM, neither showed any detonation where the timing got pulled other than shift point. Now the difference was in the AFR, the premium tune ran 12.9-13.3, and the regular tune ran a 12.5-12.9 AFR. It appears my Titan runs a bit faster in the 12.5-12.9 AFR range. Anyway, I thought I would share my findings.
