I have an injen short ram intake, custom side exhaust no resonators, Stage I, AGP WGA, MSD ignition, coil, and wires. I am using the adjustment nut on the wastegate to control boost. I am currently spooling to 18psi and holding it almost to redline. I have no surge taking place. I am wondering if this is a safe psi to run at with my setup or should I drop the boost some. I get alittle drop off at redline between 17 and 18. Should I lower the boost until I get Stage 2?
