Exhaust pop at high boost
My exhaust started popping at 22psi and it seems like it correlates in my log to a 12.1-12.2 lean spike. The popping seems like it lasts longer than the lean situation.
Does this sound lean enough to cause popping, or does this sound more like spark blowout? There is a very noticeable loss in power while it happens. It is very short lived. Plug gap .035 Obviously the answer will be easy to figure out. I just haven't had time to test since I added fuel in my map. Asking everyone here makes me feel proactive. :) |

12 to 1 isn't terribly lean. Are you running stock coils? Easy enough to find out if it's blowout. Regap your plugs smaller. It will take 10 minutes.
I had to run a .022 gap on my stock coils to avoid blowout at 20 psi. |
I'm running the toyota cops. I think it is blowout, but we will see.
