need help understanding tuning
2014 softail slim with a stage 1 - V&H BSS, dealer upgraded aircleaner, fuelpak
I'm not sure I understand Fuelpak vs Dyno Tuning from a dealer.
the fuelpak sets the bike after a stage 1 to give the bike the correct air/fuel ratio....?
is that what they do when they dyno tune your bike at the dealer?
should I think about having my bike dyno tuned by the dealer?

If you are done with mods a dyno tune is fine but if you make any future changes you will have to dyno again. With a tuner you just change the map. The Fuelpac will work with a stage 1. If you add cams I would not use a fuelpac. PCV, Powervision, Thundermax are better choices.

The map that came with the FP3 was an outstanding upgrade over the dealer installed Stage 1 remap - which IMO was crap.
At this point I have no plans to spend the money and have it dyno'd, as I can't imagine it would be worth the additional cost for what little extra I might gain over what I have now.
After all, the V&H maps were developed from bikes that were dyno'd using similar hardware.
The bike now has noticeably more power, oil temps are running 50° cooler than the dealer remap, and decel pop is a thing of the past - it's 100% gone.

The biggest difference is that the Fuelpak has a generalized map for the air cleaner and exhaust you have installed. A dyno tune is where your bike is run on a dyno and the O2 content of your exhaust is measured and the fuel map is custom programmed specifically to how your bike runs to give it an optimal fuel/air ratio across the board. If you were to want a dyno tune than a flash type of tuner would be a better option, and that's a whole other discussion. With just exhaust and an air cleaner you should be OK many people have run these for years without issues. If internal engine mods are in you future (cams, big bore....) than upgrading your tuner and a dyno tune will be required.

I have a similar setup as you, a '13 Slim with the V&H BSS, and an S&S Super AC.

Most people think getting a bike in the dyno is for absolute power. (that's really just part of it)
Think of it as going to the doctor once a year.....you may feel fine but he may catch a problem.
Same with your bike.....a dyno check up can give you peace of mind knowing your bike is running at its best.
Canned maps are sometimes good, many time terrible!

May want to clarify which Fuelpak the OP is referring to. FuelPak or FuelPak Fp3? I assume he has the original FuelPak, not the new one. ???
