A question for the tuners out there?
But since the BO is naturally asperated, how soon do I need to get it tuned. Our local Harley dealer has a great tuner guy but I'm not a fan of the the bike on a dyno since I will not be seeking every ounce of horsepower the bike can deliver. They offer 2 tuning options, $550.00 and $650.00 tune. It does pop and gurgle a bit on decelleration like most untuned bikes do. Do I have other options just to get the air/fuel corrected without being put on a dyno? Surely it wont hurt to ride a month or 2 till funds allow some sort of tune. Thanks for any help here.
the thing works great when you follow the directions.

While the ECM can account for some changes in the VE (volumetric efficiency) of the engine, EPA has made sure that HD engines are lean from the factory, and you have increased the VE of the engine (air cleaner & exhaust). Where the ECM can't handle the changes, will be at the high rpm, high load areas where you need the tune to be good... Remember, the open loop portions of your tune will be lean (outside basic cruise areas), and the closed loop portions (cruise areas) are controlled by the OEM narrowband O2 sensors. They are only accurate between 14.4:1 and 15.1:1... Anything outside just cruising along on flat highway, and you'll be pretty lean...
The statement in bold, however, is a matter of opinion....
For a different opinion...
The FP3 certainly isn't the "most effective tuner" out there... I know of no dyno tuner that uses an FP3 on the dyno for tuning.... there are, much better tuners available. A PowerVision Tuner or TTS Tuner are the top two.....
I've never used an FP3, but it's hard to imagine that it could be easier to use than a PowerVision Tuner, which I use. No, I can't use my phone to tune my bike, but get ready for a shock... the ONLY thing I use my phone for is to call or text people... so as one who doesn't need/want his phone to be able to function.... I just don't see that as a plus..
Obviously the best tune would be a dyno tune, from a competent tuner...... unfortunately, in my area, I know of no good tuners, so I'm on my own....
My choice, in lieu of a dyno tune, I got a PowerVision form FuelMoto. You get a canned map for your mods (from either FuelMoto or DynoJet), do a couple auto tune sessions (actually kind of fun to do but not necessary), and you end up with a very good street tune... If you run into any issues, you can send a data-log to FuelMoto and they will address your concerns, issues...
IMHO..... the PowerVision would truly be the only tuner you'd ever need to buy.... I bought the tuner, $199 for a license to add my 2nd bike, and I've added three, close friends' bikes (@$199 each) to my tuner, and I flash their ECMs for them when they change/add mods.... And, if you ever find a good dyno tuner, many can/will use a powervision on their dyno....
Good luck with your decision....
