fuel pump is stock. Injectors are stock. Everything is stock except the things I mentioned above in my post. OK i saw that the MBC is a Greddy and is connected to my Greddy Profec -01 so I am guessing its part of the the whole thing. I want to boost higher then 7psi cause I need to. Oh and the crank is forged only and put in by the dealer I dont know about internals but it has lifter tick big time

. So how much should I boost safely with the mods I have so far. Big 16G , Profec e -01 , Apexi N1 full exhaust , ACT 2600. What should I be boosing ? Dont want any problems with the engine for now so dont give me a huge number
Thanks
