For one I'd make sure the FPCM is programmed correctly I think it's 1 credit with hptuners. Other than that verify the aux pump is turning on, it's low enough in the tank to not be sucking air and the hobbs switch or whatever you are using as signal to turn on the aux pump is working. Are you using the stock SS pump? This should be able to be figured out by your tuner, if not you need a new tuner.
