    Thanks for your kind words.

    If I understand your first statement / question, it relates to how the additional low-end torque would affect riding on surfaces with marginal traction?

    While I agree that too much available torque could present a challenge on low-friction surfaces, I don't think that this is really the issue. Tire selection will be more critical.

    As we know, traction between a tire and the road benefits from long intervals between combustion cycles, which is why a single cylinder four-stroke bike at low RPMs generally will hook up better than a 4-cylinder at high RPMs on dirt or why 4-cylinder Jeeps do better on difficult off-road than V8s, etc.

    So a triple is not the ideal off-road mount. However, in marginal traction situations, the lower the RPMs the better the rear tire should hook up because of the wider spacing between combustion events. Therefore, assuming that the bike has a decent rear tire, I would think ability to smoothly apply power at lower RPMs would be more of an advantage than the disadvantage of having too much torque.

    Makes sense?

    Very nice write up indeed! I am a fan of PC's but I have to say...I have the Leo on my 2013 Roadie and had the dealer install the Arrow map. Mainly for warranty reasons I guess. That being said I love it. Drivability wise it does everything you mentioned above with ease. I get about 44 average MPH but sometimes higher, sometimes lower based on speed, wind, etc etc. It seems I get a minimum of 150 miles before the light comes on with anywhere from 30-50 miles in reserve based on what the bike's computer says in the "Miles to Empty" screen. Roughly 190-200 miles per tank. Honestly I am really ok with that and it's no muss, no fuss. :D

    I hope you get the PC dialed in! :clap

    Thanks! You certainly went a much easier route than I did with nearly the same result. My mileage is low-to-mid 50s but our riding styles and environments may be different.

    A few weeks ago, I had the opportunity to ride a 675 Street Triple with Two Brothers pots and the Triumph aftermarket map. It ran great, low speed torque and pick-up were impressive.

    BTW, no dialing in required for my set-up, the wide-band oxygen sensor ensures perfect fueling from the very first mile.

    Cool deal! And for the record, I THINK most of the PC guys say with auto-tune to make sure and get a good BASE map on the bike and than let it do its thing. keep us posted on your results!

    About 10K miles have passed since my last report on the PC V and AutoTune. No problems or issues at all. I've ridden to sea level and 12,000+ ft elevation and experienced perfect fueling everywhere.

    So in conclusion, I remain very pleased with the upgrade.

    old post.. but I was looking for information on the Booster plug, as these are now available for the Tiger 800.. so hoping to find out if they are effective or not.. my 2012 Tiger runs very well, but it does have a little bit of stuttering as I call it, when rolling off the throttle and quickly rolling back on again.. which is common in slow speed, rough terrain kind of riding..

    not bad at all, really but looking for an easy cure if one exits, and one that won't cost me hundreds of $ and hours on the dyno

    I am quite surprised that DynoJet has not come out with the O2 sensor that is made to fit the 12MM bungs. New Harleys also have the smaller O2 sensors. Perhaps its just a matter of time.

    DynoJet does not make the oxygen sensor, it's third party, Bosch, I believe. To my knowledge, wide-band O2 sensors are larger than narrow-band units; perhaps due to the technology inside?

    Have you talked to these guys?

    I see you don't want to spend a ton of money on dyno runs, however, they may have an affordable canned tune for your ECU that meet your needs.
    I have only chatted with them over email however Nels, seems rather knowledgeable about the Tiger.
    A coworker has great things to say about their custom ECU Tuning.

    I have a 2015 and from 15 on the ECU is locked down, so I would need to pick up a power commander if and when I wanted to uncork the XCX.

    I might do that.. normally, I'm a firm believer in not messing with fuel/ignition, as long as the bike runs well.. some folks like tweaking and playing with their tunes to get "optimal" performance, or in some cases, to fix an issue, mine runs great about 97% of the time for how I ride other than what I mentioned previously, and some occasional mild popping on decel, but I get decent milage smooth, easy starting hot or cold, strong acceleration for the most part.. but heck, maybe they can recommend something that touches up that remaining 3% without adversely affect the rest.
