Gonna give it another shot as I love how the motr picked up everywhere, but can't handle the drop in run time. Any one else seen this happen? Most I heard gained run time with this pipe.
Thanks
Is that after you retuned? I run either the 086 or Sirio 2013 and haven't noticed a big fuel mileage difference with either. 8 minutes or more with either pipe. Can't imagine it dropping that much with the Big Boy.
