Adam helped set up the switch for the two step on the supra but no matter where I set the kpa for in the stage 1 on the i boost it only goes to about 7 psi even at higher rpm. The max timing retard is set for -13 deg not sure if thats it I will try -15 to see if it helps just not sure. I have it to cut spark and trying it on pump gas so I think this is ok? I may hit you guys up monday if pfs can not help.
