Finally got my Super ATV Stage 2 tune installed. Drained gas and put 91 octane in it. Got to say it definitely made a difference. Easy install, quicker response and I shut it down at 55 mph and was still climbing. I have a duraclutch and hoping it will handle the extra kick. Haven't had it in the trails yet but I think I will be very pleased with it. Definitely woke the 570 up.
