thanks brother...nice nice run!
Thanks for all the nice comments guys!

I mixed in the race gas right at the track. I did not change my user TQ settings. It seems to adapt pretty fast.

The ECU may have adapted over many runs though. The ET was best early in the evening while traction was at a premium, while the best MPH was later on, after quite a few runs. Maybe due to ECU learning the race gas, or maybe due to the decrease in ambient temp. The butt dyno felt faster as the night went on. 3rd to 4th felt sick...

What's involved in this? Your car seems to be running pretty lean as-is according to your dyno sheet posted on dragtimes.com.

20 runs? Seemed like 40 You definitely got your money's worth and I don't fault you for that. Good job! Car was very consistent compared to some of the high dollar cars out there..

Not sure how lean is lean for these cars. Might have to ask shiv about that.
It seems to be that raising the user TQ on my car past 94% slowed me down..
