First long road trip on the PPK... can't seem to get her to push past 9.5psi (p3cars vent gauge). Any luck for anyone else pushing beyond that? This is from dropping to 5th gear at 55mph and going to the floor and waiting. I think I need a charge pipe but the wife wont let things stray from warranty for half a second.
