Spark blow out. Lower the gap on your plugs.

Alright! I’m running NGK7s gapped at .028 currently.

Lowered gap to .025 and seems to be perfect to 7k

Are u running ngk bpr7es? If so, changing to a non protruding plug might help as well with spark blow out. Br7es.

Yes I currently have the NGKBPR7ES and I gapped them down to .025 and haven't seen the same problem yet with moderate pulls and a dig to 80. I'll have to hit the highway to really see if its fixed... But I did pick up some NGKBPR8ES just in case. Just doesn't seem like two stages colder would be ideal with my current setup

I agree, change to BR7ES and gap them lower. I typically run anywhere from 0.019-0.025 depending on the amount of boost.

Glad to hear your problem may be solved.

I had the same problem. switched to non protruding plugs and gapped them at 0.025 and it went away.
