Regapped 534 at .026 getting ready for the GH tune to arrive and just realized that GH uses 542. Ugh. Should I change the plugs now?

Yes ... We run the load high enough to need a colder plug. It is cheap insurance.

Ok thanks, I will. I swapped the tsat from 160 to 170 in preparation for your tune. I should have checked about the plugs at the same time.

Matt, I’m running your tune and I didn’t specify any type of plug I was running, if I swap to 542 do I need any change In calibration? Thanks.
