Hey guys can y'all help me out. I just installed a power commander pc5 on my 2011 Rzr xp 900. I'm running a true dual lonney tuned exhaust and a uni flow air filter. And since instal my check engine light is now on and it's running like crap. It idols up and down. Then when I give it has it dies out?? I thought I might of had bad gas so I siphoned all the fuel out and put 93 Octane in it. Could my plugs be fowlled from bad gas causing this or do I just need a tune?? Thanks for any suggestions and help I'm stumped
