Just wondering if someone can help me out.
Got a GT4, engine wise itz relatively stock. When it was imported was informed it had a full thru exhuast, but when i got it checked out to my disappointment it only had a muffler (Fucken Liars ). Still got stock cooler,turbo, etc. All its got ATM in engine bay is a HKS pod. It has a Blitz boost controller n just wondering wot the most safe amount of boost to run would be. Currently running 10psi.
Thanx alot.
