Wondering if the stage 2 map on the jb4 for N63 is supposed to be 20psi? Says 6psi over stock but that doesn't tell me target psi. I'm reading that a safe psi is 20. But I'm getting 14-15 max at times. Wondering if I'm missing something. Am I supposed to use a different map or use a backend flash.

Based on your profile, you have Non-Tu which right away tells me that your diverter valves are shot. They max out at 16psi and then tear after a some time. Same happened to me until i got the ones from N63intake.com Now i can hold boost no problem at all.

Additionally, i recommend getting a back-end tune.
