We have a 112 on a 2650 here that makes over 1000rwhp and the 112 worked great for about 1000 miles or so then has progressively got worse. We have tried to flip it over and we have the same result with 1516 codes. I have put a video link here of the blade under a WOT pull along with a log and tune file. 2016-mod-55.hptREDUCEDENGPOWER.hpl
