It's a 2008 teryx it's got a dynatek controller on it
I serviced it 110 miles ago when I became the owner

Big difference between 53 and 58, 58 being closer to being right

STumbling on top end is usually a sign of a rich condition, first check to see if one of the choke cables is binding and check the Y in front of the gear shifter there is a Y wrapped in heat tape and wire ties, cut the top one and free up the cables. One of the sheaths could have come out too.

Popping on decel is a lean condition.

The stock coils do not perform well at high rpm. My 08 had the same issue- upto 50ish it was good, push to 63, started missing, soon as it backed down it ran fine. It was not hitting the rev limiter either. LS coils cured it. Do make sure the jetting is good, little rich robs some power, little lean robs $.
Good luck.

A hard starting Teryx is a sign of valves defacing.

IF it is hard to start all the time, adjust valves and see if it starts better if so then get prepared to replace the valves with aftermarket valves and springs.

Again, you are welcome to call me on this Wed.

It ended up being the valves were extremely tight causing low compression
