searched the forums, but just wanted to clarify. I got an A-spec 500r and am going to swap out the twins. I dont have the fuel system yet but i am going to order one. How much boost can I run with stock rails and injectors just to see if the car runs well after the install. Car is not a DD so its not going to be driven till the fuel system is installed.

My current set up is. Stock rails, injectors, Nippondenso fuel pump, boost controller, ported wastegates on twins, full 3 inch exhaust, power FC, FMIC, dual intakes, airpump removal. running 12 pounds Thanks.
