| When decelerating with a manual car, sometime a "duk duk duk" sound is heard, or if you accelerate aggressively say in 2nd gear and let go of gas it does happen, is that safe? |

| Its a sign of excessive fuel puddling thats why youre getting the backfire. Throttle back on your fuel pressure regulator and monitor it on your wide band |
