ok so i just bought an 05 wrx yesterday and noticed it doesnt have a bosst gauge. that didnt bother me because i just ordered one today so its no big deal. the question i have is what should the stock boost be set at?
what is the stock boost for an 05 wrx?
i talked to a guy at subaru and he siad the stock wrx's should be running at 9psi.
is that correct?
also what is the safest but highest amount of boost to run on the wrx without upgrading internals? what bolt ons would i need to support this?
