[RB25DET backfiring at high rpm full throttle]

-change plug gap to 0.9-1.0 mm because too small can not ignite all of the fuel - smaller stands up to more boost physically only

(think of a birthday candle and a harder blow is more psi)

-call your tuner and tell him to tune your car properly and stop running so f**king lean

-do you run ~400hp at 15 AFR? I don't believe that you know the "final tune" without taking pics yet you have pics of your "base tune" If so repeat above point with added profanities, if not then we need pics of the actual tune you're using not irrelevant bullshit

-rb20det = coilpacks w/ ignitor pack (NOT built in)
-rb25det s1 = coilpacks w/ ignitor pack (NOT built in)

-rb25det s2 = coilpacks w/o ignitor pack (built in)
-Buy some proper injectors not the retarded 90s shit
-Or ignore all above and stop being a pussy scared by a pop noise, belt the piss out of it and buy another when it leans out and f**ks you over because of your idiotic tuner
