Recommendation Request: 600-700whp K20 Turbocharged using E85 Fuel

Want to get an idea of what plugs to run in a turbo K20 with e85. Highest power should be 6-700. Had it on the dyno last season running ngk bkr8eix plugs gapped at .018. And around 25-26 psi, it started breaking up like it was blowing out the spark. Tuner believes I need to run a different plug. Wanted to know what other people are running

Shouldn't your tuner have figured that out while the car was on the dyno?

You don't need a different plug, you need enhanced ignition to work with the COP setup standard on the K20. M&W or Okada Projects comes to mind.

But I'll be honest, I've never seen a K20 with that power level need anymore than a BKR8EIX IK24
