Can you reflash a 06' 900 RMK from SLP's reflash, back to stock reflash?

Can you reflash a 06' 900 RMK from the SLP reflash, back to stock reflash / flash? I'm having a hell of a time figuring out why my brand new 06 900 RMK is cutting out at about 5,200 rpm's, and again at 6,600 rpm's. It seems to happen right before a bit of a power band (6,900rpm and up) kicks in if you know what I mean. I had it at the dealer a few times to go through the process of elimination and so far no luck. So here's what I'm thinking...

What I'm considering doing is trying the sled with the stock pipe and can to see if it still cuts out. I'm no mechanic, but I'm pretty sure we would need to reflash it back to stock specs from the SLP reflash specs if we try this option.

My sled has done this cutting out from mile 1 to mile 300, and has had the following mods since mile 1, so I don't know if it would have run right had I not put any mods on it.

-SLP high altitude head
-SLP single pipe, y pipe, and can
-V-force 3reeds
-Fire and Ice airbox
-Aside from that the other modes are venting, touque arms etc. etc...

No codes are being thrown from the computer. The dealer has checked the following sensors; egt, tps, & air temp. They have also re reflashed it with new reflash codes from SLP. And they checked the v-force reeds. After checking the sensors and reflashing it, they told me they thought it had to be the SLP head, so I put the stock head back on, and it still cuts out right at the same spots, around 5,200 rpm and 6,600 rpm. The motor will come right out of it, snap to life, and run spot on at all other RPM ranges right up to 7,900 without missing a beat. I'm trying to convince the dealer to put in a new ecu? They do not seem to think that could be it.

This cutting out at these RPM ranges is driving me nuts. My 05' 900 sled, with the same mods except for it has an RKTEK head, runs perfect at all rpm ranges. I want to use the 05' more as a backup / wifes sled as it's miles are getting up there.

I'm looking for any other potential issues to run past the dealer to use in the process of elimination. Thanks in advance…

Thanks for all the thoughts on this. Am I correct that if you run the stock pipe, and a SLP can and SLP head you do not need to reflash? If this was the case, and I could get my sled to stop cutting out I might stick with the stock pipe if I could at least not have to use the boat anchor of a stock can.

What do you all think of going with an after market boondocker box or equivalent? I believe these boxes work with changing the fuel air ratios? The dealer told me that putting something like that on might do the trick. At around $300 I'm not too excited about going that route though, and I just want the sled to run well without having to tinker with a boondocker box all the time if that would be the reality of it.

Any other thoughts on this??

RMK900204 are you suggesting to have it reflashed back to stock and then put a boondocker type box on it? What do you mean by "TFI settings"? I'm assuming you mean the setting on a boondocker type box? It's frustrating as my 05 900 with the same exact mods except the head is an RKTEK head runs great with the SLP reflash. I'm shaking my head asking what gives...
