HD Super Tuner vs Power Commander

I'm have installed the Rinehart slip on muffler on my 09 FLHX vs the Scream'n Eagle. Now I'm thinking of installing the HD heavy breather air cleaner. It's not worth a $150 one time remap when I plan on more performance up grades in the future. Next upgrade will be the Stage III after the factory warranty.So I'm thinking of going with the Super Tuner or Power Commander? Your thoughts please. I'm new to the computer era on bikes so I need some ideas.

I would reccommend The Thundermax ECM with auto tune, it converts your bike to a closed loop system where the ECM adjusts automatically to any changes you make. No need for a Dyno tune, and its not a "piggy back" module like the PCIII. I went through this same thing and juggled a few products back and forth such as the PCIII and Fuelpak from V&H. Ive been very happy with my choice in the THundermax. Its more expensive than the PCIII, but youll end up paying about the same anyway when you add on the cost of Dyno time.

I was reading in some rag that the stock HD ECM maybe able to remap to your changes without an upgrade. Damned if I can remember the magazine though... May want to check it out before spending the money on something you don't really need.

That's just it, they can be remapped at $150 a pop. When I asked the dealer about the air cleaner upgrade along with the mufflers that I already have they said that it would cost $150 to remap the computer. That means that everytime I perform an upgrade I have to put out another $150 for a remap. With the HD Super Tuner you avoid this cost? That's what the dealer is telling me? I'll get a clear understanding of the remap today since I have to drop by the dealer anyway. I understand the old saying "If you want to play you have to pay".
Thanks for your input.

Ya misunderstood... Since you got an '09, your stock ECM may be able to remap itself (in 15 minutes they say) to your new pipes and air cleaner. No need for a new ECM or having somebody remap anything. The stock ECM has a lot of play area for changes without having to be upgraded. I believe I read this in American Iron.
Personal experience? Nope... I got a carb. But I'd try out leaving the stock ECM in and riding it for a while to see what happens. Maybe do a plug chop to see if you're on the lean or rich side.

Rockslide ,that's exactly what the tech said at the dealer. However, he did recommend the remap. So I'm installing the air cleaner this morning and I'll ride it and see if it makes a diffference. The dino charts that that I've seen for this upgrade shows a increase of 10 ft.lbs. of torque and hp. I should feel something! Thanks

You guys might not have seen an earlier discussion on this general topic, and IMHO our member rjrivero might be the local subject matter expert. Check this thread
