I don't know much about these sleds yet I just bought one, but I think most people stock at lower elevation get about 120 psi of compassion if I remember right, they aren't a high compression engine, and 1200 miles isn't much really, my sled I turned up the oil injection now, I want a average of 35:1, I hear factory runs like 60:1+ for. Emissions, and loading a sled up more with boost that's not going to help longevity. I know the newer a/c run a higher comp engine, like 2010+ so you can't compare to them, and ski doo's are like 160 psi, I wouldn't replace pistons until they hit 120 psi, so a 40 psi loss.
