Ok. I have a supra and the stock boost level was 14.7psi. We no longer have a stock engine but have fully built the supra block with je pistons, headwork etc.... and strapped on a DBB76mm turbo on it. We are fully built from the driveline all the way to the intake. What is the goal in tuning for WI or metahnol? Do i keep it from injecting until i see the egt's climb wich will indicate the ecu pulling timing from knock? Supra ecu's don't monitor knock unfortunatly so we can't see what is going on other than by watching the egt's climb.
