Spark Blowout?
So on E-85 occasionally I get the motor falling on its face about 4k RPM, right as I am getting into high boost. Motor shakes and sputters I think I am getting spark blowout. Gap is set at .035 boost is around 15lbs, does the sputtering and shaking while falling on its face sound like spark blowout?

Yeah I did break in and tune on .035 put about 1300 miles on the car and just this last week started sputtering and falling on its face over 4k rpm when not completely warmed up and even after.

What plugs are you running? Try a non extended tip plug. Ive always ran the BR7EF for boost and nitrous.
