Who else is running the hmf full exhaust on there 2021 outlander 1000? Does yours backfire at all? Mine does. I'm running a rvs performance tune. He tried 3 different tunes tweaking it but still backfires when I blip the throttle at curtain times. It's annoying. But boy don't that wheeler sound good and it's fast!

I'm annoyed by the backfiring. I flashed the wheeler with the tune file for the hmf full exhaust from dynojet and it still pops. I'll be cruising along and I'll hit the throttle hard and left off and bang!

Wow.. Bet that makes them squirrels run! Three different tunes and still doing the same. Can you take it to someone with an ATV dino? Maybe find someone with BUDS program to help diagnose the fuel mix and come up with a custom tune? About a $1,000 for the setup but I am working on getting the software and connector kit so I can use a laptop on my machine and maybe other BRP machines in my area for a small fee.

Unfortunately nothing up my way. And I'm not really computer literate lol.
i have a 21 outlander 850xt and i put the yoshi slip on silencer and pv3 tune on it and it does same crap u talking about . i have been in contact with dyno jet and they have sent me 5 diff tunes not including the 2 that came on pv3 and we canot resolve the pop i took my spark arrestor out and put the stock exhaust and stock airfilter djt on it and seems to do it less . but vary frustrating . the quad absolutely rips but seems as they should be able to lean out that area mine is 0 to 1/2 throttle blips and u get one loud pop not evey time .if i figuar out how to make it goaway i will post again

For one they cannot void warranty unless they can prove 100% that the mode was the failure of the machine... Getting off the shelf tunes from companies like dynojet is just a shot in the dark as they are not 100% fine tuned for your setup. You need to grab a tune of a place like motorsport addicts that dyno tests and fine tunes the tune on the same setup you are running
