well after seeing that the turbo that my bro was giving was infact externaly gated, and i already bought an internaly gated manifold, he gave me a helluva deal. instead of giving me his t3, hes giving me his t3/t4 thats internaly gated. with this bigger turbo i obviously need more fuel and my question is, will my dsm 390's and stock pump be enough to be safely boosting around town on 6psi(is this even a safe boost level with no tune and stock internals?).?
