I loved my viper with the stage 4 flash, but am looking at getting the sidewinder. I want more top end and the better shocks the ltx le has. I wish I could hold off to 2018 to see if there are any issues with the sidewinder but it's so hard for me to wait!
Wasn't much of a season nor conditions. My 1.7 lug track did not have enough snow depth to do it's thing and really started shucking off lugs to a point that it is in pretty rough shape now.

Just curious, Have you been real hard on the track or is your opinion that it just is not a sturdy trail track.

I just had mine reflashed for stage 4. I should have it back wed or thursday, but i wont get to try it till next year.
Just wondering, where did you notice the most improvments as far as performance is concerned.
Low end? Midrange? Top end?
Or did it seem to increase everywhere?

It is characteristic of the sno-x tracks to separate. The lugs are very stiff and hard. I'm sure that riding in low snow conditions also contributed.
I would say the response is probably the best gain. Starting is still far from perfect, but seems pretty predictable. I would be quite interested to see what happens in fall with the factory update to see how this works and if there is any benefit to merging with the EVO flash.
What factory update?
New file coming in fall (or so they say)
Can you be more specific? Sure don't want to get hopes up again if not true.

I have the 2.0 91 octane flash. Throttle response is very crisp/responsive and it starts good. Overall I'm pretty happy and would do it again.

No you read it here, someone posted back a week or two.
They claim The dealer said another reflash was coming.
I read it when it was posted but at this point i just dont care about Factory reflashes and went the evo route

I was going to wait to get a few rides in this year before I pull the trigger on a evo stage 4 flash, but a deal fell into my lap that I just couldn't pass up,(thanks Mr.sled), my sled ran great before with the ulmers intake, sandale can, and big venom clutch kit, so I was a bit skeptical how it was going to run with the flash and straight line header, but so far all I can say is wow!!, It fires up within a split second, idles great, has a deeper throatier exhaust note, and with the raised rev limiter should be way easier to clutch, can't wait for snow to start flying.

Hi Mr Sled!
I have the Evo's flash stage 4 and Evo's muffler. Now, I'm looking for the Evo's header. If I'm going with straitline's header, will I expect the same performance ? The Evo's header suppose to perform better because the long tube ...the best buck for the money for me is the MBRP's header but seems to have not gain in hp...
