Guys- First off, the best choice is to get a professional to dyno your bike. Unless you buy scream'n eagle pipes, don't get a HD flash. If you have a good engine mechanic with a dyno that is experienced and comfortable with one product, go with that. It will probably be a race tuner or powercommander. They both set front and back cylinders independently, and do fuel and ignition. The V&H fuelpak is fuel only, and they don't have a lot of programs. Remember, Powercommander is Dynojet. Dynojet makes the dyno that is at most everyones shop. If you have a HD dealer that has a real good dyno guy and doesn't charge you for 5 hrs at $94/hr. like my local dealer does, go with him. Otherwise, find a hop up shop local that has a great reputation from people you know, that has done similar set ups to what you have. If you to your local HD dealer with a high flow heads, cams, big sucker filter, and thunderheader, what are the chances your local dealer has done a tune with those mods? Something to think about.
