Stop right where you are. The 08 you are currently riding has different gearing than the bike you test rode. The rear belt pulley on your bike is a 66t and the touring bikes since 09 have been fitted with 68t rear belt pulleys. Yes you can put a 68 on your bike without a belt change. Do a search on here and other places for the info. Less than $200 and even if you decide to go big bore you will still want to fit the 68t rear belt pulley. It makes a noticeable difference.

The water-cooled exhaust valves in the 2014 models have enabled Harley to increase CR and use better cams. So the clue is in that sentence! If you use a 107 kit, such as the FM suggested, you will get increased CR, better cams, plus a reprogrammed ECU (via a PCV). Sorted!

A combination of things. It has a better ecm and new software strategy 614. It also has new cams that are close to the SE255. 2° more duration on the Intake 2° less on the exhaust. It doesn't have as much lift as the 255 and has little more lift than stock. These are not official numbers, but numbers I have found on internet and we all know these have got to be accurate. They do have more compression. Our dealership put a stage 1 with 2 in 1 and SEPST with upgrade map on a 14 street glide and says it runs ever bit as strong as a SE255 stage 2 upgrade to 103. It is the combination of all of it.

Andrews 48s and a proper tuner and tune. Your PC3 and true duels are killing ya. But yeah, bore/headwork/compression/big cams will walk the dog (at least in the harley world).

There are 3 things that produce torque: Stroke, Compression and Exhaust Velocity.
Increase any of these 3 ( or all of them,) and you increase the torque it produces.

Good luck on what you choose but a rear gear change and some 204's, good exhaust and tune, I think you'd be happy.

My 09FLHTP is in for cams right now!
Really happy with the way the 103 runs, but you can ALWAYS use a little more.
I'm now running FM's stage one setup w S&S SPO's.
Picked up a set of the dreaded SE255's Take offs from a SE motor for $100. Local Indy is installing them, should have it back next week.
ALL my riding is 2K-3K, wind it up to 4K when I'm in a hurry. This should be my last upgrade. Planning on riding this one into retirement!
My only other concern is if FM's map isn't as perfect as the Stage One I am running, may add AutoTune to the PCV and dial it in myself.
Did this same thing to the wife's 02FLHPI, fuel mileage was 36-38, she is now running 43-48 w/PCV and AutoTune. Recent trip down to Alabaster Caverns in Ok, we both made 48-53 mpg coming home on Ok. real gas no ethenal.
