Hey guys I have an xp 900 with a MCX turbo installed. So far, the turbo has given nothing but grief. The first weekend out I got into a little water and fried both Ecu's, the polaris and the mcx. Talking to MCX getting into water with the ecu should not affect it as long as the ecu is installed properly with the drain hole down so it can drain, which it was. So, after I got that all fixed I drove out for maybe 20 miles and all the sudden it would not run good at all. I have not got into the engine yet but have found it to have 175psi on one cylinder and nothing on the other. The piston seems to be fine so I am assuming its a valve issue. I will let update once I get into the engine. My question is is anyone having any good luck with the mcx kit on the xp? Is there anything I can do to make it better, HELP PLEASE!!!!! I had an mcx kit on a 800 and loved every minute of it, the 900 has been a complete hassle and regret!!!!
