I have a 2012 rzr 900xp with KMS intake and yoshimura rs-2 exhaust. I run the Dobeck Gen 4 AFR+ fuel controller and love how easy it is to use with my very limited knowledge of tunning. I bought my exhaust used which came with a Power Commander V and my question is am I able to run the Dobeck as my fuel controller and also use the power commander to control the ignition timing to get the extra rpm?
