Misfire 180 mcxpress nytro

[Stricklandj]

2013 nytro xtx with 180 mcxpress kit getting misfire on WOT. Running at sea level and getting 8.5psi boost. Too much boost cause misfire. Plugs gapped at .26.

I'm not a Nytro guru but remember something about when the Nytros first got the optional MPI turbo it was for 6000 ft and above. Are you running any race fuel with it ?

My Nytro did that, the plugs looked fine but after we swapped them out it ran like a top again.

Is it a misfire or are you on the rev limiter? If a misfire try gapping the plugs tighter. The boost may be blowing out the spark.
