My ‘24 patriot boost has been the most underwhelming sled I’ve had, 800 miles of issues and poor performance. I’m pretty new to the aftermarket game, clutch tuning etc but this issue is starting to feel like a clutching issue. Before I go spend money on a kit I’d like to hear troubleshooting suggestions in case the problem is elsewhere or if these things are really that bad stock.
The issue: the sled seems to be pretty heavily affected by altitude in regards to max rpm’s and power. The higher the elevation the lower the max rpm’s and overall performance. I know that’s usually the case, but I figured a turbo sled would do a bit better with elevation changes. My elevation range is 7200 ft to 10500 ft
What I’ve done so far: for aftermarket parts I have a gen 2 silber can and mtntk under hood intake. I’ve taken it to the dealer and they replaced the injectors and injector harness as well as a watergate actuator relearn. The sled felt a little snappier after that work but is still not where I think it should be.
When I got it back from the shop I test rode it and at 7200-8000 ft I only had a max rpm’s of 7700 and could only build boost halfway on the boost gauge. I then switched from the stock primary spring (165/310) to a mtntk spring (150/320). At 7200 ft I could then easily pull 8400 rpm’s and had 3/4 boost on the gauge, riding up to 8k ft the max rpm’s only dropped a little. Then I took the sled up to a starting altitude of 8300ft and went up to about 10300 ft. At 8300 ft I couldn’t get past 8200 rpm wide open throttle on the trail, and that dropped to 7700 rpm at 10300, and the boost gauge didn’t show much more than half except when I let off the throttle.
When I bought the sled it had the high elevation clutching which, the Polaris website says is for 5k-13k ft.
The question is are other people seeing the same thing on their stock clutching set ups with the optimal altitude being lower than 8k ft? Or do I have different possible issues I need to look into?
Thanks for any insight
