10 VIN's for Service functions such as resetting service reminders.
But you missed the sale of $319
NO riding here, way to cold and to much snow!
Let us know about the Brentune

Took it out for a shorter run today (still pretty cold) - Brentune Stage 1 - everything reported is spot on: huge midrange improvement, pulls smooth and strong all the way through the rpm band now, idle is perfect (not cold sputtering), quick shifter is smoother.
Good for you mang, its wild how much more grunt it has. Be careful. Mine wheelies too easy. Have you done full exhaust yet?

Good to hear! Are the intake flappers open all the time?
Will be with the kit and stage 2. Not stage 1

Yes it's a power wheelie king, if you're using the wheelie control what is your setting (race pro)?
Nope - I'm one of the few who likes the stock can. I may get a pipe next year but does anyone really need more power on the street?
I have it set at the lowest wheelie possible. Max propulsion..
I took my sc project slip on off after i installed the headers. It was crazy loud. The stock can is just fine and it looks good too. I might sell the sc project can. The headers on this bike make the 2nd most notable performance gain. The 1st being the tune.

You can have flappers stay open through software with Stage 1, you dont need the kit and stage 2.
Right on. I spoke with brentune i may have misunderstood. Maybe they will chime in.
@BRENTUNING from @Ravenbravo. "You can have flappers stay open through software with Stage 1, you dont need the kit and stage 2."
When I purchased the tune a few weeks ago I asked if this was a thing. iirc I was told no. Insight would be great.
BTW LOVE THE STAGE1 ITS FANTASTIC.

Fwiw i would Id pull the trigger on headers. Less $ than a can more performance and weight savings. Totally worth it.

I emailed Brentune quite a bit about this for stage 1. Yes, they can make flappers stay open through software. If you buy the Kit, you remove the flappers all together and you get some more air. That is for the person looking for every once of HP they can get.
Their response about flappers open with stage 1
"Yea I can do that with stage 1 no problem, if forcing open the flaps I recommend doing the IAT for best most consistent power"
I bought stage 1. But its winter time with snow and Im still not at break in miles.
So when winter is over I will get bike serviced, rev limit removed and update the ECU. Then I will have Bren tune send me the stage1.

What is weight savings?
I work as an environmental engineer but I'm not a tree hugger. With that said, I truly hate following anyone with an open pipe and breathing that crap (especially trucks). It's inconsiderate

11 lbs saved for headers alone using stock can.
IIRC the stock exhaust cat and headers is 23/24 lbs the stock can is 4lbs = +/- 27/28 lbs. The system i installed is 2lbs for the can and like 7lbs +/- for the collectors = 9lbs. Saving quite a bit of weight. This does a decent job explaining it. Better than I could.

These are examples of why weight savings is important to ME at least.
As for riding behind someone with open headers -no cat- ...welp... give them some space or pass them....

A bike doesn't spew that much HC, but the trucks with cats deleted are really bad - one of those probably spews out as much as 100 "normal" cars, if not more
10 lbs on the street isn't going to mean much of anything, and it's carried low on the bike. Aftermarket exhaust is also warranty issue
