There is an update for the 2022 900T-R if you want it and you experienced the inconsistencies reported. I cannot recall the exact update, have to go and back read it.
But it seems that those that are more in the know of the 2022's & BRP in general, timing and boost are removed when certain temps are reached as a fail safe, temps that are way too conservative for most and why being able to get into the locked ECU to change those thresholds, like you can on the 2021 and older, has become a hot topic.
Plus some suggest the intercooler cannot keep up with the hot temps either that the turbo is producing, is another issue.
Nothing some $$$$ cannot fix - if you want to spend it that is......sadly, this should not be an issue though considering the flagship the new 900T-R engine set up and what the Mach was supposed to be, in some peoples eyes.
