13 psi on an 11:1 compression is risky. I'm running a JDM ITR motor 11:1 compression on 9 psi peak (steady at 8 psi) on my set-up. The key is a great fuel managent and great tuner.... dyno tuning is highly recommended.... all the info about my Teg is on my site.... We decided not to pass 7800 RPM on the dyno. I was still making power but we chose to just simulate the gain and tuning pass 7800 RPM....
