I have a 17 850 turbo and one side is down to 105 compression. Apparently BRP pistons are backordered until July. Anyone know where I can get a pair? Or are there any aftermarket brands that I could trust on a turbo sled?

I bought a used turbo 850 with 700 miles, ridden at 6000 elevation, where I'm at 12000. Turns out the fuel pump went bad and my afr was too high on WOT climbs. I hit knock sensor 4 times. After replacing the fuel pump it still has a horrible bottom end bog. We are talking 1 1/2 seconds before the sled hardly moves. Took it to my dealer and had the compression tested and one side is 105. I'm really hoping that takes care of it. I'm worried there is more going on because while 105 is low, I'm not sure it would cause it to bog this badly.

What's normal compression @ 12,000 feet? 150 psi - 36% = 96 psi ?
Actually closer to 101#.
Air pressure's kind'a like figgering compounding interest.
