Ragrep,
If you wouldnt mind, would you please elaborate on the believing in the power commander more for me, I would like to understand why you feel the way you do about this as well as where the 10 percent number you chose to throw out comes from.
Power Commander 5 seem to range on the internet from 299 to 385.
I paid 325 for both of my TTS
I paid 365 for both of my SERTS with Cables
In my area South East a dyno tune ranges between 200-400 with Power Commander and Local Dealerships here charge 250 to 400 dollars for SERT Tunes depending which stealer or shop you go to.
To me the dollars are minimal in difference

A person can save a little money on the tuning using the Power Commander depending on who tunes it and how much they do, but to have an added device that rides on top of the ECM and if it craps out how do you get home depending on how lean the motor is without the power commander?
I am not saying you cant get a decent tune with the Power Commander, but your rationale and statements such as the 10 percent number you are using to make your point in my opinion is from left field. Alpha N vs. Delphi Pressurized Manifold?
Having the ability to do more if you want / needed too, why wouldnt you want to have this for a good tuner to leverage as well as for the future / choices when we are talking nominal dollars over what we have already spent on these bikes and accessories and chrome for them.
