I have a 2014 Polaris RZR 4 1000 that I recently installed Trinity Stage 5 Exhaust and an S&B particle separator. The ECM was tuned for the Trinity exhaust. I had it out at the dunes over president’s day weekend and this was the second trip with the new configuration. it ran great the first day but on the second day it started cutting out once the engine got hot when running at about 3/4 throttle. I have re-tuned the ECM, checked the spark plugs, ran all new gas with sea foam. Any ideas?
