you know whats funny, my injectors did the same thing. 2 of the new injectors i got(550cc) where bad and stuck open. i was really scared lol but xact dyno got me new ones in no time. i think you should be making more then 300 hp. on 6 psi i made 360hp to the hubs. on my old threads i have the dyno sheets posted up. i have my maf sensor before the turbo. i did this for a couple reasons. all turbos will blow a little oil into the charge pipe at times. which might mess with the maf readings, and also its thought that drivabitily will be better due to less air turbulence before the compressor. i maxed out my maf at 8psi. it was reaching a full 5v there so i will need the hpx maf when i get it tuned.
i did see the knock thingy on uprevs site. thats pretty sweet! i do drag the x every now and then. its fun to see peoples faces when they see me staging at the track. it ran 12.96 at 114 last time i had it out on 8 psi with the stock trans and motor. im hoping for 11's on 14psi
