0.022 might still be too small though and could be the cause of the misfires and stumbles. |
with the M2 being forced induction with a turbo and tune, wouldn't we naturally want slightly tighter spark plug gapping ? since there is more boost pressure at 22 PSI, I would need to make sure I get a spark between all the compression. I feel like going slightly smaller would help, but obviously not to the extreme of .018 like how the shop did it. I feel like .023 would be the perfect medium
