Looking at your profile it looks like you have all the supporting mods to run it at higher psi. You really are missing out on all of the fun! I run 19-20 psi on 93 octane with Aquamist on my GT2530's. Without Aquamist, I'll run 17-18psi in 90+ degree Miami heat and humidity with no problems. Especially since you have a JWT ECU you have plenty of room to increase the boost safely.
