Rzr 1127 code. Changed boost controller, blow off valve, clutches and belt, determined waste gate is operating properly (crack pressure), still throwing code. Im running 28 STU paddles it seems to do it in 4X4 . I have took it to the dealer 4 different times and they can’t find anything wrong with it. However, mine still runs perfectly fine. No change to motor or gearbox and standard tune. If you own a RZR, this probably doesn’t surprise you. I have received a 1127 code on my rzr. If your filter has been clogged for very long you will also need a new fuel pump as it wont sustain the right pressure after getting overworked with the plugged filter. The turbo is working and so is the blow off valve. of Polaris.
