2nd and 3rd questions to this. Did you purchase the maptun hardware and cable, or do you have a dealer/buddy with the tool that helped you flash your sled? Looking into it, but the $1200 price tag for the hardware and license feels steep for a trail run.
Are you running a clutch kit or stock clutching with Maptun?
Definitely need a clutch kit. It is what is going to make or brake the tune purchase.

Okay lots of questions way more bottom end power is there by 5000 rpm and it’s down right nasty hard hitting. Im not a mountain guy by any means but in chest deep powder it will catwalk and flip over if your in it too long. The boost builds fast and its instant lift. It’s fast like stupid powerful I can’t imagine needing stage 2.
im using Ibackshift clutching and joe has me working amazing. Down ! Clicker up weight, sleds fastest it’s ever been.
I ordered my maptun direct so I could flash and log myself, regardless of the price dont bother with bikeman.
I’m 1200’ elevation and I’m 91 pump fuel ONLY.

Awesome feedback, thanks TurboJ!
Rode headlight deep powder in South Fork today. Stage 2 Ibexx, Big Johns clutching and a SLP can ran flawless. Better bottom end than stock, smooth all the way through the powerband, and pulls hard at the top.
Day 2, still flawless. 8000 rpm 6.5-7 pounds of boost.

I'm running the Sibler Stage 2 and it runs great same as stock down low and pulls noticeably harder up top. I ride with a 21' Poo 850 and a 20' Expert NA and it dominates both power wise. Even at lower elevations (1500-2000) The difference just grows with higher elevations as it should.
I
The problem the guys are seeing with the Bikeman bigger tunes is in the 5000' and above, sled makes good HP in the lower elevations so its not as noticeable, but when you get higer in elevation you can see it shows its face a little more on the transition from N/A over to boosted...... And yes if clutching is off its even worse....
I
Would really like to try the Maptun against my Stage 3 Bikeman, flash sled and leave the clutching exactly where its at and ride my zone to see if it pulls the weight i have loaded up in it. That would tell me if its more or less power, but hard to fork out another $1000 just to try it.......
Day 3, lots of tracks and the snow began to set up. Tune and clutching totally consistent, no hiccups or bogs.

I would bet my left nut it would pull more weight.Would really like to try the Maptun against my Stage 3 Bikeman, flash sled and leave the clutching exactly where its at and ride my zone to see if it pulls the weight i have loaded up in it.

Knowing the work & effort that Jamie has put in, as well as staying up to speed on his build, I know that MapTun will be my flash of choice as soon as my break-in is complete.

maptuner stage 1 ran perfect all weekend in Revy , ill be adding more weight , things fly and runs flawless , very happy

Glad to see its working for you. I can honestly say I gave Bikeman my all to make it work right, I reached out to Joey many times explaining the situation, explaining what was happening, asking for help and crickets. Anything I have asked of Maptun I get an answer by the next day and they have been nothing but helpful. I finally emailed Joey again for the last time politely explaining to him that I was moving on from his tunes / company. I don't expect a reply however I let him know how much better the Maptun files work. It's too bad he wasn't willing to work with me and try to get his tunes to come around.
To the guys who I have steered to Maptun I truly hope it meets your expectations how it met mine, its black and white obvious in my sled which tune works.

for sure tune is amazing ! by joey are you talking about the bikeman guys or joey from ibackshift? if ibackshift hes been awesome with me for response and help!
I
Ibackshift Joey calls, emails ya back..... Bikeman Joey...not so much....Unless you are directed to there sales dept...then they talk to ya..$$$...

Jamie, can you bring me up to speed on what you didn’t like about the bikeman tunes and what the map tuner does better?
I have been very happy with my bikeman base tunes at stage 3. But I will say, my 21 runs way better than 20.5. 20.5 has a big lack of mid range, you can literally hear that it’s not making boost like the 21, it won’t pull the weight or make the speed rhe 21 does. Setups are identical. Torque link tells me that the tunes are identical in both sleds. Wondering what the deal is

The bikeman tune has no bottom end or mid range and needs huge engagement or stupid weights to make it zing and then it goes kinda. The maptun hits hard LOW and carries you can hear the boost by 5k rpm so its almost always there. And it comes on HARD and FAST the bikeman tune has no bottom / mid by comparison.
I should have known from the beginning when I had to click UP to make my bikeman tunes work. It has so much more low end power now and it carries on up top it doesn't go flat with a big sorta WAAAAAAAA at wide open. It now TRUCKS to full RPM and keeps pulling doesn't lay down like a sick horse.
So to recap with the maptun - more bottom end / more mid range / more top end all on stage 1 for me. My sled on stage 1 maptun would destroy my sled on bikeman 30 hp tune and that's a fact.

That’s cool!! Glad it’s working good for you!
What track length sled are you riding at what altitude? What kind of track speed is it producing in the deep in a big hill?
