Bottom bog back 2015 M600 Sno Pro here’s what I’ve done.
I replaced the clutch and springs. TSS still might be but can TSS cause it to be intermittent? I Runs polaris red Race oil can this be? I run Red Race oil in my 12 M8 no issues. Can the oil cause this? I hear run C-Tec oil?? Any help please.

There was a thread on this earlier and it had to do with a dampener on the fuel rail. The 2018 has the dampener, some guys were updating their sleds with this. I never really heard any results, to me when the subject goes quiet it is usually fixed. I don't think the oil will be the issue unless it sticking the power valves, why not just run the c-tec and eliminate it. Install a tether and by pass the tss something else eliminated. Did you check the power valve cable length and ensure they are both to spec?

If it happens primarily at the very beginning of throttle movement I would agree with the TSS being a factor. At the very beginning of throttle flipper movement the thumb needs to be perfectly aligned with the flipper so that the flipper pin moves squarely to the switch. If not the instant bog will happen. Not all switches are as sticky (sensitive) but on my machine it was very sticky when new and it took a bit for me to get familiar with the new thumb to flipper relationship. It does not happen at higher throttle settings because by then there is enough pressure to keep the pivot pin fully engaged.
