I was reluctant to buy a pocketlogger for the longest time.... but I can say for sure that its the best money spent on any sort of monitoring for my car. they're not even that expensive, DSMtuners has the whole thing on sale, often less than 100...Plus it helps you diagnios problems, and helps you know right were that limit is... I think every motors different... based on compression, and how clean your combustion chamber is, amoung other things... I personally got away with 16psi on my B16G with a cheap front mount on 92... but it changes with the weather what you can get away with...
