I currently have the stage 1 upgrade with the AGP WGA, Injen ram air, Custom 2.5 inch side exhaust, MSD ignition, coils, and wires, and was wondering what is the highest that I can set my boost to with the stage 1. I currently have it set at 16 psi to redline. With the stage 1 is it safe to boost higher than that?? I am currently running 13.4's and 13.5's in the quarter.
