I know this thread says 350+ but my question is geared toward 295-300 whp. I have 55k miles, Cobb stage 2 and want to get a stronger bov or bpv, a Cobb up pipe and intake & air box and possibly an ets tmic. I'd like to keep boost at 18.5 with a custom 92 octane tune. I'll be doing this before the end of the year. Should I replace pistons? Should I replace head gasket? What gauges should I add? I don't want to add gauges to look cool, just for safety.
