    HELP!! nnbs turbo setup with fuel problem

    ok to start off i did a Trick Performance front mount turbo setup about 4 monthes ago including a couple supporting fuel mods, walbro 255 fuel pump, 44lbs injectors. The truck has done flawless up untill yesterday i poped the code p2635 and p069e and my exhaust went from a full healthy sound to a hollow empty sound with a little hesitation. With all this being said it still runs great and feels right it just sounds like hell and is pulling codes. So today i put a new pump in and i still have the same problem. could it possibly my tune and it reacting weird with the Fuel Pump Control Module.

    you tune won't just change by itsself. If you already had a 255 and the 44lb injectors then swapping the pump wont affect the Tune either I wouldn't think. Did you make sure your exhaust didn't come apart or you dont have a huge exhaust leek on the cross-over or some thing like that. Just some thoughts

    yea the exhaust was the first thing i check and i even ran open down pipe and got the same thing. But it wouldnt pop the codes p2635 or p069e if it was an exhaust problem.
