my car is m6 on a stock tune w/ full exhaust and other minor bolt-ons w/ a nx single nozzle wet kit(125 shot) FYI......the car runs great when i spray it in 1&2 but in 3rd and sometimes 4th @ higher rpm's it kind of stops working....i know this sounds kinda of weird but it is the problem i am having...maybe it is breaking up and i just can't hear it....but it seems that the motor just stops working and making power.......could it be an o2 sensor??(i do have rear o2 sims) or does it have something to do w/ not getting enuff fuel??....any ideas would be great....

 

What was your bottle pressure when you were spraying it?
