I believe you guys are talking about 2 different issues still. What handsome is saying was a real issue with the 2014's if the sled got vertical enough in a climb or wheelie the ecm would detect a low oil pressure and shut it down causing major problems if in a chute. For the 15's Yamaha changed the baffling in the oil tank so when the tank is horizontal all the oil can't flow to the top of the tank very quickly and losing suction. They also did some programming to give slightly more time before going into derate. You can get all this done for a 14 Yamaha was offering the programming update free of charge and then you would have to buy the tank baffling.

My boosted 174x3" 2014 viper had updates and still would get the oil light on a steep climb and go in limp mode.
Got rid of that toad(It handled like a 676lb toad) and got a 15 and built it up, the 15 has the same Boost-it turbo, roll over, more $$$$$ and ... does not leak oil anywhere but did have the oil light come on after a moderate climb and long wheelie. Backed off and let the front come down, light went off and kept on going. So there is still an issue.
