What was the engine speed at peak power? Is the engine an F20 or F22, and has it been bored or stroked? I'm guessing the injectors were the limiting factor for E85, was knock the limiting factor for 93? Did you record the IATs? What was the difference in ignition timing?

 

engine speed at peak power was 8,650rpm. Pump tune the peak power was at 8,800 rpm. Unopened bottom end F20. Injectors are the limiting factor on e85, with knock the limit for 93. I would have to look at the logs for IATs. For timing differences the tuner said there wasn’t a blanket amount across the board
