I have a 2014 1000 with a turbo and a PC-5 with an Autotune. Had a few intake leak gremlins that I now have sorted out. It runs real strong, pulls hard.
Problems are, it backfires on decel pretty loud. Just a couple of big pops when coming down from a short full throttle run. I can’t seem to find any exhaust leaks at all so I’m not sure. It didn’t do it for the first 50 or 60 miles.
Also, after running it for a while, when I slow to a stop, it’s super lean, like around 17 or 18 on the A/F and won’t idle right and just quits. If I shut it off for a second, then start it back up, it’s smooth and sitting right around 13 A/F.
The other thing is, under very gentle acceleration or even just a straight cruise speed, it surges. If I roll into it just a bit to accelerate, it’s ok. Anyone have any idea what might be causing these problems? I’ve turboed a lot of vehicles in my life and never ran into this stuff. Thanks, Dan
