Dalton QAY70, TB 270, need your help

[Fleecer]

Stock springs. This is what I have on a 2018 Sidewinder with an 1.75 back country track with a stock can. This morning 11 degrees, flat hard pack trail. Pin it runs right up to 8950 rpms, pulls like a freight train. Smile from ear to ear.
An hour or two later snow is lose, warmer by 5 or 10 degrees. Sled will not pull 8000 rpms. Not smiling from ear to ear. 3rd day in a row it does this. I can barely out run a vector (disappointment) to say the least. This has to be in the clutching (springs) is what I can figure. Any help with you experts out there? Help me finish the season smiling again please.

Here is what I would do:
Start sled and plug muffler with rubber/leather glove. Sled should stall or show exhaust leak if any. Make sure there are no exhaust leaks.

Get a hold of a boost leak tester and make sure there are no boost leaks.

If you dont find anything conducting tests above, find someone with a flasher and read the ecu for codes. If codes exist, clear them, run sled and recheck.

Good Luck!!

I am dropping the sled off this weekend at Priceless Performance. They should be able to figure it out quickly. They are the experts. If I can feel that pull a couple more times this winter, It might be enough fix to get me until next winter.

When doing #1 (plugging exhaust) engine should still within about 5-7 seconds if there are no exhaust leaks. If it doesn't stall and continues to run, somewhere there is an exhaust leak.

Keep us posted on what they find.

Hope they find that issue quickly so that you may feel that pull once again, and this time all day long or whenever you choose!
