Thoughts on changing the spark plugs to the 542s or similar with this tune w/ a tighter gap?
If the truck is having misfire issues in boost then it'd be a good idea to run a plug with a tighter gap. We haven't seen anything during Stage 3 map development that would require or benefit from a tighter gapped plug. It probably won't hurt anything but I don't think there's too much to gain from it either.
