Please tell me you running the dry kit nozzle before your mass air flow sensor? If its before the throttle body but after then sensor then your truck isn't compensating for the nitrous and your leaning it out......

 

Well when i first had the kit yes it was ran before the mass but then i moved the nozzel a had it tuned for the nitrous when i got my cam stall ect. An it hits way harder night an day diff. I know what detination sounds like though truck did it a couple times when i had the kit setup before the mass
