There are reasons why most generic tuners lock customers out of modifying their tune, generally it's because they don't want customers blowing motors and blaming the tune.
It's a personal option I guess and how hard you want to push your car. For most people they are happy running 13-14psi but I want more out of my car. I understand the safety aspect and it was you that said the N54 is almost bulletproof. I know my car can handle 15-15.5psi with my mods, cool temps and a resonable octane level to support. I know your a track guy but I don't track my car and on a daily basis I run autotune which see's around 13psi. Once I have meth and CPS I should be sweet to run about 16.5psi.
