I was wondering witch is better a fuel pak Or the power commander or any other programmers? I have a 012 street glide 103ci slipe on pipes and order the kn filter but programmer but up in the air on witch one I should get.

I personally like the harley plugin. I think that it is the best solution as it is made for your bike and engine. The power commander is a lot of work to get it right, dyno and more dyno.

I utilize both approaches. Betty has the super-tuner while Spinner uses the packaged program from Harley. And both bikes run great. Power, no flat spots, and they pull away cleanly from stops.

However, I believe both bikes needed the differing approaches. Spinner has a standard, modern, rubber 1200cc Sportster engine. We did the simple stuff. Pipes and air filtration. This winter, an oil cooler. My wrench got the correct download from MoCo and installed it.

Betty's engine. on the other hand, is extensively modified--and not all within the same year. I picked out performance options that pertained to me, not Peter Fonda. She saw the dyno twice. The 95-inch kit alone was installed the first year using standard synth oil changes until 6K miles of break-in. Then the fun began! And with those necessary miles the dyno tuning didn't stress the engine components.

I happy with what I did and it has paid benefits. I believe that my last peeve--Spinner's heat--will be lessened by the oil cooler. My overall advice is still build a bike for yourself and you alone, use good parts and talk to your wrench.
