Is there an issue with running those gaps and / or the NKG with a Cobb OTS tune? or If im utilizing the OTS tune should is stick with the OEM plugs?

I believe my MP215 kit is OEM gap as well. Beyond that I'm not certain however.

I just changed my NGK's from .30 to .25 and it runs alot better. .30 misfired under load on the COBB stage 2 OTS. .25 runs alot better
