Normal For Car to Backfire after Spray?

[SOMBV]

I was doin a little racing and sprayed from about 40-110 and let out, car started backfiring pretty bad. Is it normal? I changed just about every Fluid in my car today just to look and everything was normal.

if there's an overabundance of fuel, it can. this is because when you let off, you probably let completely off. this cuts air off from entering the motor and goes rich for a split second and the timing increases to stabilize the idle. this can even happen when running NA.

agree on the na. Mine backfires like a shotgun for about 5 min when cold. Then I never hear it again, until cold.
