Dizzy. I am at 9.5 degrees at 7K rpm, with 27psi but...the AFR is 11.1. All I am saying is timing can be reduced to run the higher boost...not sure if that will make the most power. 3psi away from 30 is that far
@wetwea33 you have any datalogs or information from your ethanol mix tuning? PSI, timing, lbs/min?
