Hey guys my s15's a sr20de+t and I don't know what I can do and what I can't do? since I don't want to stuff my motor and all i'm wondering is it safe or not to have a boost tap and put the boost up to 12ish psi. The previous owner said it was tuned to 6 psi and he was certain but some reason it says 9 psi on the dyno sheets. And it's getting up to 9-10 psi when looking at my boost gauge, so is it safe or not? any information about +t's and all would be excellent thanks.
