HELP: 2008 DS 450 Stalling out

I have a 2008 Can Am DS 450 that I recently aqcuried. She wont stay running however. It gas a big gun exhaust. When i start it, it will slowly wind down and shut off. If i start it and give it some throttle until it gets warm, she will stay at a rough idle. If i stab the throttle and let it rev down and stab again, it quits immediately. I have a service manual. I have 112 lbs of compression, 350 kPa of fuel pressure, valves are in spec, and i recently replaced the oil pump and oil pump idle gear. I feel that the ECU was not programmed but i do not know for sure. Im running out of ideas and need help!!!
