I've been hearing this weird noise and I can't figure out what it is, I recently installed the 6 pound pulley, it's usually when it's hot out and I'm in the throttle, it's like a weird fluttering noise, almost like a miss
Any ideas?
did you get a tune....
what did you gap the plugs to
definitely could be spark knock / detonation.
6lb needs colder plugs like the ngk tr6 and a tune with less timing than stock to be safe.

Yeah, I'm running a custom, haven't changed the plugs yet, I'll try that first
