Plug Gap

thanks guys....been busy at work damn it, hence the late reply.
when I had my foot up it doing the staging burnout it sounded like it was on the limiter, but had not reached the set limit. even my tuner didn't pick up on that.
have set the gap to 28 now and sounds cleaner and crisper even at idle. a mate with a screw blower suggested 34 35.
going to a track meet on weekend coming so will let you know the difference.
cheers once again. this forum is awesome.
