I have a 92 GSX and just got a Hahn super 16G installed, but the car keeps cutting out at about 15psi and at about 5,000 RPM! I called Hahn and the ytold me I needed the 625cc injectors and I got them but it didn't seem to work. I als ohave the Hahn fuel pump and intake and exhaust. What do I need to do to make this work?
