Hey i am just worried that my turbo wont spool up with my stock d15b7 intercooled but i heard it will be okay with 7 psi of boost. I also have another question.... i have 2 blow off valves; a rfl, and a greddy type s. I havent tried them out but i was wondering if any of them would be loud and sound cool with 7psi??? please help thanks need to know cause turbo is going in friday

thanks
