Already Misfiring??

1ndonlySG · 07-10-2014, 02:13 PM

Hey guys, so i have a 2013 n55. It has a little over 5k miles. I have a jb4, catless downpipe, bms intake, FMIC, and chargepipe. The car at some point has good power, then my car barley goes. Everytime i drive WOT, my car misfires and i start over boosting. Has anyone experienced this?. I did a test run with a couple of my friends with EVO's with couple mods without a turbo upgrade, i only took it by half a car to a car. I know for sure i should be taking it by more. Please let me know, thank you!

Did you decrease the gap on your spark plugs to ~.022?

Then that is porobably your problem. Spark is being blown out with the higher boost.

Yes, that would be the first thing to try if the problem only happens with the tune.
