2010 dragon idles like crap

[Smithy]

At home it will idle at proper rpm, but once im up at high elevation it will barely idle. had the dealer check the tps and they said it was fine , but im not sure if they knew what they were doing, got the sled back home and noticed they forgot to put my battery back in! was i pissed! Any info would be apreciated.

If your compression is up it is probably is the tps. Mine was same way and when we did a Good job of adjusting it run like a top and pulled stronger.
