Well I'm just gonna have to crank mine up a little more! There are a few of you running 23-24 psi and no one's thrown a rod yet, but I have to say these kind of boost pressures really make me nervous. Maybe I'm just thinking of all the older turbo cars that had factory boost more like 7 to 8 psi and I need to get with the times.
I wanted to come back to my earlier post above and say that in light of Preloader's head gasket issue with his 24 psi tune, I am not going to go any higher than my current setting which peaks between 20.5 and 21 depending on ambient temp, baro pressure, alignment of the planets and whatever else the ECU factors in.
