Pacific Northwest Premier Mobile Motorcycle Dyno Tuner


We have the ability to make Harleys run like they were designed to. The key to tuning a Harley is getting those big v-twin cylinders balanced. The engines are basically two separate engines sharing a crankshaft. From the factory these were programmed with a single fuel map, but with this design individual fuel maps for each cylinder are necessary. With the 2007 and newer models, O2 sensors began to be utilized to ensure a leaner motorcycle that was more emissions friendly, however this had negative effects on the motorcycles.

So with a tuning device, preferably a PowerCommander, we are able to tune and adjust individual cylinder fuel timing, accelerator pump and rev limiter extension on an individual cylinder and individual gear basis. The PowerCommander also includes O2 sensor elimintaors that will eliminate the closed loop function and allow us to tune the individual cylinders directly off the head ports where the O2 sensors used to be. When we take a completely stock Harley, install a PowerCommander and properly balance the cylinders, we’ve seen a minimum of 45mpg and 10% power increase to the tire. This also greatly improves low rpm throttle response, mid-range and top end horsepower. Reliability is also improved greatly because the cylinder temperatures are decreased substantially. Most heat shields on exhaust are no longer even needed.

There are many types of programmers out there for the Harley’s, but with the hundreds of Harley tunes we’ve completed over the years, we have found that the PowerCommander is the most user friendly of them all. It offers the highest tuning resolution, meaning the ability to more precisely tune the fuel maps, and is one of the most affordable tuning devices for Harley Davidson motorcycles.

The same process above is applicable for Buell motorcycles, one difference is we use a Buell specific tuning device, the ECM Spy, when a PowerCommander is not available. We have done lots of testing, troubleshooting and research on Buells, and can help with most, if any, of your Buell issues.

    I have a 2001 Road King that is modified. the engine is 95inch it has ported heads with larger intake valves, Hi lift Cams .575 inch, Horse Power Inc 51mm Throttle body with larger injectors and 2 into 1 exhaust. I am having a hard time tuning it. The fuel injection is Magneti Marelli system. I have Harley race tuner to install new fuel and timing maps. The main issue is there are only about 4 base maps to start with and there all based off stock fuel injectors. Is this something you could tune? If not do you know someone that could? The Delphi system has thousands of maps but not my Magneti Marelli system.

      Iam trying to look into the S&S vfi ecm is a direct replacement for the mm ecm not cheap around 650.00 for the open loop and 900.00 for the closed loop. I cant find much info on the net about the system. Not cheap unless you compare ti to the tmax at to have the mm.

    Are you able to tune .MT8 calibration files? I’m using TTS Mastertune because I don’t want to add another box under my seat. I’d rather modify the files and flash the stock ECM. I have a 2012 FXDF with a hypercharger intake, V&H 2 into 1 Big Radius exhaust, and no other mods. I’ve flashed the stock calibration to a similar modification, but need to eliminate a small decel pop at higher rpm’s.

  4. Are you able to tune .MT8 calibration files from TTS Mastertune? I have a 2012 Harley FXDF with a hypercharger and V&H Big Radius 2 -1 pipes. I have added a base calibration file for a similar configuration but experience some decel popping a high rpm’s.

    Hi Nels,

    Thanks for the great tune on my 07 Street Glide. The bike has never run better. I could feel the difference on my ride home.

    Great work and great customer service. Will definitely recommend you to all my Harley riding buddies.

    Thanks again

    Got a 2014 Bagger, 110 screaming eagle in it with pro super tuner, rinehart exhaust. Harley shop has a crappy tune on it, decel pop, dies at idle. You have a tune for this? Vancouver WA.

    June 11, 2014 at 12:36 PM

    • I do have the ability to tune this. I’ll be down in Vancouver this weekend actually, give me a call or email if you’re available and we can work on smoothing that out for you!

    I have wanted this done but not able to afford it I live near portland oregon in clark county battle ground wa
    I see your visiting portland in September and want to know what I need to do to arrange this I still have the factory exhaust and air filter does this matter? My bike is a 2012 harley 103 road king.

    August 1, 2014 at 9:09 PM

    • You will need a fuel programmer like a Power Commander installed on the bike, exhaust and air filter don’t matter, we tune and calibrate your engine to what you roll in on, and even stock you’ll get huge improvements before and after the tune. The cost is $225 as the twins take a good bit more time to get dialed in properly. Email me with more questions or if you want more details at

    Will you be in the Kenmore/Bothell area anytime soon? I’ve got a 2005 Buell XB9SX that has a K&N filter, Jardine exhaust, and a Buell race ECM. It runs ok, but has always seemed to be not quite right – it sometimes makes valve noise under hard acceleration and seems to run hot in general.

    I got a 2015 Street Glide with the stage 1 kit. V&H Slip Ons. Arlen Ness Big Sucker Air Cleaner. SE Pro Super Tuner. Thinking about taking out the CAT out of the stock headers. Do I need to tune it after I take out the CAT? If yes, can you tune it?

    August 31, 2015 at 3:05 PM

    • The answer is yes and yes. That will make a big difference in your heat and air flow and we do tune for that.

    have a 2011 48 with v & h big radius pipes what tuner would be best for you to tune on this and should I wait to have you tune it after I get an air intake,im just afraid of how lean it is know and what damage it could be doing im in oly

    November 1, 2015 at 11:06 PM

    • We also tune down at Redline in Tacoma on Tuesdays, you’ll want to get a power commander and we do a individual cylinder balance tune and get it dialed in perfect for you! Send as an email to schedule a time to come up!

    I have a 2009 xl1200n sportster
    Had installed
    We pro racing do high performance cam also known as 536
    10:50.1 high comp piston
    Roller rockers
    High volume lifters
    Head work by j precision racing from Quebec Canada
    Harley offers no map for the 536
    The Dyno work done at the dealership only produced 81 horse at 6500 rpm , I thought I would have got more also have performance machine hp breather and Vance n Hines short shots staggered
    The bike does not run well between 2 & 3 thousand rpm
    With the se pro runner I raised the timing and seem to have made some gains in better power within this rpm range.
    Can you help me with a map? Timing and ve tables feel the biggest issue is the timing.
    Help please

    July 17, 2016 at 4:23 PM

    I would love to employ your services for tuning my Buell. Only problem is I’m about as for away as I can be (NC). I’ve heard of some that were able to do remote tuning. Are you able to do this or do you have any suggestions on anyone on my coast? (Xopti is closed)

    August 14, 2016 at 7:56 AM

    • Unfortunately that needs to be done in house on our dyno.

    I have a 2015 street glide with rhinehart mufflers and Arlen ness big sucker stage one a/c,what tuner would u recommend,what would be the cost of dynotune to get my bike running like it should?

    December 9, 2016 at 9:51 PM

    • Highly recommend the power commander to get the best possible tune for your bike. Full custom dyno tune for that bike is around $250.

      December 12, 2016 at 6:24 AM

  22. Sean

    Is it $299 or $499 for a Harley dyno tune?

    December 11, 2016 at 5:56 PM

    • Harley tunes start at $225 but we’ve never had them go that high before. The dealership might but we don’t.

      December 13, 2016 at 7:05 AM

      • Sean

        Thanks, I’ll be in touch after the engine build end of this month.

        December 30, 2016 at 8:01 PM

      • Sounds great!

        January 1, 2017 at 6:38 PM

      • Sean

        Can you tune with the Power Vision vs Power Commander?

        January 2, 2017 at 4:41 PM

      • Yes. We recommend the PC5 with fuel and ignition.

    Hi thanx for response.

    My bike is 2009 xl 1200n
    Se 10:50.1 high comp piston
    Se high performance cam the 536
    High volume lifters from se catalog
    Se roller rockers
    The heads were done at Jpercision racing out of Quebec canada.

    So the dealer did several dyno tunes and I felt that something was not right
    At 3000 rpm the motor suddenly behaved different.

    I used the se pro tunner and looked at the map.
    Noticing Chang in the timing table.
    I looked at the factory map for the 551 wich is the base map they used and found 7 degrees difference from one cylinder to the other and it was back n forth no reason I could understand.

    Have talked with several people shop advised me to advance timing to 30 degrees by 2500 rpm
    Made a big difference.
    I have played around moving the timing up n down a couple degrees at a time.

    So I know am sure there’s a issue there.

    So what I am asking for is a map for the timing for the 536 cam.
    I do understand that for some reason this cam must be dyno tunes as there is no factory map.

    Is it possible to get one from you.
    I do understand that your business is of this nature and your source of income.
    So be it a purchase is a reality for me if I can’t get one for free.

    Thanx for your time and responding to my questions.

    I recently purchased a 2009 harley davidson xl1200l sportster and would like some advice. As far as horse power gains do you have any advice as far as an exhaust, air intake and fuel management system. I would like to have the bike tuned by you after I throw the new parts on, that is why I am asking for your advice. Do I need to get a fuel management system like a power commander or can you guys just alter the mapping. The space is limited on these bikes. I have a power commander 5 on my road glide and it is wedged in tight.



    March 11, 2017 at 5:48 PM

    • Yes we’d want a Power Commander installed and then we’d be able to perfectly tune the fueling for the bike. Air filter and exhaust are the two major things, once you pick what you like give us a call and schedule an appointment! Most exhausts will perform well on the bike.

    I finally had an opportunity to check my mpg after you tuned my 04 heritage softail.. Prior to your tuning I was getting 33-35 mpg during gentle riding …. Now I’m getting 40 mpg hot rod riding….. Passing is really easy now that it runs so much better.. Looking forward to not having to look for a gas station every 120 miles… Great job will definitely recommend you guys when asked for referral other than a Harley dealership..

    Hi there
    I got 2016 street bob with my power vision.
    So can u guys tune with the power vision?

    Hey, Nels!

    Finally bought a bike and it’s a 08 Fatbob with an 113′ and Rinehart Dyna Crossbacks

    I bought the bike used and Don’t have any info on the motor other than it’s a SE Stage IV 113.

    I know I’ll need to buy a PCV but is there anything else you can think of that I may need?
    Look forward to getting tuned with you soon

    July 5, 2017 at 7:09 PM

    • PCV is the best for the bike and we can get it dialed in with that perfectly
