My 2 Cents;
For the folks just doing A/C & Pipes, I think the FP3 is hard to beat, a little fuel adjustment in the proper places is all that is required to have the Bike run smoother, cooler, adjust TBC if necessary, and get rid of decel pop,,, very easy to use,,, No Dyno Required, Bluetooth to Phone a nice feature...Used properly, the #s should be close with a Dyno Tune on an otherwise stock bike...
If you know you are going no farther than AC & Pipes, I like the fact that the FP3 is easier to tweek (by the average end user) than a "canned map" from full featured Tuner...
All things considered, Dyno Tunes can be an expen$ive pita, finding the "right" Dyno Guy, Purchasing the Tuner that he "feels comfortable with",,, Make an Appointment, Travel Time, Down Time, etc...etc...
I have personally witnessed an A/C & Pipes only Dyno Tune by a "highly respected" Dyno "guru" (only uses TTS) that had decel pop that sounded like a .22 going off

... when the Customer called him about it (3 States away) he wanted to blame it on gas,,, I was riding with him and filling up from the same pumps, the '09 was running perfect

To get his tune "fixed" he had to travel back & forth from 4 States over, for several hours of test rides to try this, try that,,, No Dyno, the "guru"was "busy"...
The time for a "Full Featured" Tuner / Dyno Tune is when Cams, Displacement, Heads, come into the equation... The simpler "Auto Tune" stuff cannot compete at this point,,, there's no getting around it...
There are a lot of Dyno Operators going to Techno Research,,, just as easy (if not easier) to learn / use, more flexibility including Diagnostics and Digital Technician Capabilities... and wait,,,wait for it,,, No "Lockout Feature"
JMHO Your results may vary
