And also so when someone has Nos backfire does that mean not enough fuel or…

some say i have to much compresion and thats whats makes it backfire and that being said it will be fine for the moment.

anyone??

If you don’t have a vacume line from the nitrous soleniod to your FPR your kit is not complete. Dry kits use nitrous to increase fuel pressure. this is accomplished by pressurizing the vacume line to the FPR with nitrous. the amount of pressure increased is regulated by a pill(jet). Just like the regular nitrous line. :rant:

running the juice with no fuel management/upgrades? thats just silly. all i can say, is detonation is not your friend, not in the least… hope youre internals are ok :wave:
