So I bought a rjwc slip-on mud edition exhaust for my 2021 xmr 850. I got a tuner from a friend. I found out all those tuners each exhaust producer uses are from the same place. I did some research as the best settings out their and I still don't think the bike sounds perfect. There is a tiny pop going from the yellow to red settings on the tuner. Should I lower or increase?

Any other suggestions or what settings y'all run would be much appreciated :)

get rid of the Blinky box tuner and do it properly.. The Blinky box turners just fool the computer setting you need to have your unit flashed or get a PV3 and flash the computer yourself. On the older machines the Blinky box tuners were the norm. But now your trusting your investment on a inexpensive box that just intercepts the signals going to the computer and adds or removes fuel basically.

I agree with zrock. Get your ECU flashed or if you plan to do major mods down the road spring for the PV3 now.
