Stock 04 with gutted exhaust ran 118. Added ECP down to 113, shimmed secondary with 5/16 lock washers runs 115 now. Runs 10100-10200 out of the hole, climbs to 10500 by 115. (25 degrees and hard pack. Secondary all stock in stock no.3 hole. Stock primary weights with rivets slightly drilled on all runs) Belt squeals at idle since i added 5/16 washers, tried different belt still does. Belt rides about 3/32 over. Any ideas on how i can gain 5 plus MPH or about belt squeal? Thanks Mike
