Hey any help is appreciated, I've got a 2009 teryx fi starts right up but the longer you drive it starts to pop out exhaust, won't go over 10mph. It's got 45 psi of fuel pressure all the time, 65psi comp. valves in spec. It has a Muzzy dual exhaust, Muzzy digi tune and k&n air cleaner. I bought it like this and the Guy I bought it from says never had a problem with it. It has 99 hours on it. Any Ideas?
