Q. Can the Fuelpak increase my rev limiter?
A. No, the Fuelpak will not control/adjust idle speed, ignition timing, or rev limit
This was copied from V+H's website FAQ section for the fuelpak. Not trying to monkey wrench your plan, just want you to have correct info. Possibly there have been updates to the fuelpak and the FAQ was not yet updated? It's the last FAQ question on the site.
Good Luck

I can't remember if you decided to go with the 255's or not, if not, my guess is if you don't you should be fine with the fuelpak, just watch the low RPM roll-on's. One of the more knowledgable guys here can probably answer this better. I have those 255's in my 110 bagger and they are a pretty nice torque cam although I've never tried another cam in the bike so I'm comparing it to nothing except the fact that it pulls pretty good down low. I also had to add a SERT and a full dynotune to dial the bike in. It ran pretty crappy B4 the dyno.

Thanks! Some more good reading....I'm at work so that'll have to wait for tonight.
In fact I asked the dealer if this capability is recent and he said it wasn't - though 'recent' is a relative term that I didn't define during our short conversation. Recent to him might be in the past year while only 2 years ago they could only adjust fuel, but feedback from shops, customers and the market/competition encouraged them to add this feature else lose customers such as yourself and others on sites discussing controller capabilities.

If you are concerned about pining on your trip don't install the 255 cams now. Set the FuelPak up for a Stage I 103" motor and wait until you return to install the cams. V&H does have a map for the 103" with 255 cams, but as I understand it, the factory Stage II/103 ECM download is required as it will adjust the factory timing curve for the 255 cams. So, you have two choices, don't install cams now and set the FuelPak up for a Stage I 103" motor, or install the 255 cams, flash your ECM with the Stage II ECM download and program the FuelPak with the V&H FP-1106 map. If you do have cams installed, make sure your dealer talks to V&H to be sure he has the right factory download for the ignition curve and the latest V&H map for the 103" with 255 cams.
Oh yeah, don't forget the octane boost.

Yes I opted to keep the 255 cam that comes with the standard Stage II 103 kit, assuming they know what they're doing when assembling the kit and that that cam suits the needs of the majority of riders. Especially since riding a tourer I assumed a torque cam is a no-brainer when it very well may not be. When you say low end, you mean rpm up to _______'? I'm hoping its up to say 4000 rpm anyway. I'll be careful with low rpm roll-ons, even though the catalogue implies the 255 specializes in such situations, unless I misread it.
What's a SERT? A Screamin Eagle......fuel and ignition controller? When you say you needed a dyno to get it running properly, do you mean it was binging before the dyno tune or it just wasn't reaching near it's power potential?

SERT - screaming eagle race tuner , HD's version of fuel injection management, just like the Power Commander that has been mentioned. When I said "low RPM roll on's I was referring to the 2150 area you mentioned earlier, I think your already squared away on that. My bike with the 255 pulls strong from 2700 ish right up as high as I need it. It's known to drop off early but it works OK for my needs, and I like riding my bike pretty hard on occasion.
...... Good Luck!

Both, it was a bit pingy B4 tune, it could be controlled w/riding style but not totally eliminated.

Your dealer is mistaken, the FuelPak does not have the ability to adjust timing; it works with the factory timing curve but cannot change it. If you are concerned about pining on your trip, don't install the 255 cams now. Set the FuelPak up for a Stage I 103" motor and wait until you return to install the cams. V&H does have a map for the 103" with 255 cams, but as I understand it, the factory Stage I ECM upgrade is required as it will adjust the factory timing curve.
You can probably understand why I'm confused between the dealer, V&H's supposedly rigorous testing in all conditions with no problems with this setup, and the well-meaning advice from experienced people on this forum.

He must have programmed it for a 103 with 255 cams, he said it would have been a 1690 legal download for 103 and 255 cams so assuming the dealer is going to do the factory Stage I ECM upgrade to adjust the factory timing curve.

The Stage II 103/255 kit requires the separate purchas of a factory ECM to upgrade, upgrade, among other things, the stock ignition curve; different from the Stage I ECM upgrade. The appropriate factory ECM upgrade accompanied by the appropriate V&H fuel curve for the Stage II 103/255 cam kit should work for your motor but I would still take the octane boost along on the trip.
Honestly, I am growing weary of this thread but feel obligated to try and keep you from shooting yourself in the foot.
BTW and FYI, the SERT is probably the best fuel management system available today. The TTS Mastertune is an upgrade to the SERT and was developed by Steve Cole, the same guy that developed the SERT. The TTS is more user friendly and has more bells and whistles than the SERT but, at the end of the day, both will provide an optimum state of tune; the SERT is just less user friendly and takes an experienced tuner to work with it.
Tuners like the FuelPak and Power Commander are throttle position based while tuners like the SERT and TTS are speed density systems. The FuelPak and Power Commander are "piggy back" systems that "trick" the ECM into delivering fuel. The SERT and TTS actuall re-program the ECM. The only advantage the piggy back systems offer is that should the Fuel Pak or PC fail, you can remove them and run on the factory ECM and get home or to someplace the piggy back system can be replaced/repaired. If a SERT or TTS ECM fails, you are dead in the water until you can get a new ECM.

Thanks. Hopefully I can still benefit from dyno time (tuning) with the FuelPack...if only to adjust the fuel if necessary.
