Just curious if there is a big difference as far as performance, reliabilty etc between these, or is it just a matter of preference. The Fuel Pak is the cheapest...is there a reason? If it helps any I have the SE slip-ons, and will hopefully be adding the SE heavy breather soon. Thanks for your help.

 

the only one of those that allows tuning is the power commander. other tuners are even better.

 

After buying my V&H slip ons I also bought the Arlen Ness Big Gulp air filter and the V&H Fuel Pak. The fuel pak is easy to tune for any exhaust and air intake changes because you can program it yourself depending on your pipes and air mods. The V&H internet site has all the info and a video showing you how to program the fuel pak. My 08 1200 Roadster runs great and it was very easy to setup the fuel pak with V&H recommendations. You can't tweak the programing in the fuel pak but you can email or talk with V&H staff about any performance problems and they will suggest modified programing to try in the fuel pak. I am not able or want to tweek the fuel injection settings, so the V&H was the simplest conversion for me to do at home. Plus if you ever want to change back to the stock settings, with stock exhaust, you just take every off and your stock HD mapping is still in place. One last thing, the Power Commanders are very good too, but they are more expensive and you are better to let the HD Dealer install and program it. The SE is the same as far as programing, only the HD dealer can down load the new Fuel Injection mapping. Just depends mostly on whether you can or want to do it yourself or have HD do it.
