ok awsome guys learned alot from reading this thread....BUT (always a but) isnt the main point of replacing this valve to prevent boost loss from cars that are running at higher psi (chipped)? Im thinking of chipping over the winter and i want to make sure that the stock parts that need to be upgraded are. this car is my daily and im sure for most of you it is as well. just want to make sure that i dont go and spend money on a spacer that does nothing but make some noise and i already have an EVOMS intake so going ATP is not an option....... so what you all think?
