When I had my motor tuned for E85, I was under the impression that the tuner set the timing to 22* at WOT....the max boost was 17.5psi. Today I was data logging some WOT runs, and noticed that the timing never exceeded 19.5* at WOT up to redline. What kind of timing do you fellow corn burners typically run at ~18psi with a twin screw? The motor made 637 rwhp at this timing and boost level....is there a lot more power left on the table with additional timing? See mod list in sig for combo details.
