I'm running the mini maxx 300 tune and i am getting a surge at about 55mph just wondering if anyone else had this problem with the 300 tune or if i just need to update
Thanks
Thanks
you may need to update. Id call H&S and ask them. Judging by your location I would guess it is cold weather related. Some tunes have been known to have a surge in colder weather.
yes, really like them
