was wondering if any of u guys know if when they install the kit they reprogram the stock ecu or if they use a powercommander, only reason i ask is casue in teh future i will probally put a set of pipes on and use the power commander with them let me know if u know anything thanks

HD will have a flash for the ECM. However I would recommend a PCIII, because after the flash you will still probably be too lean. EPA restrictions are hard on performance. Check around, several vendors of teh PC11 will program it for your modifications and send it ready to install. It will not be perfect, but it's a drastic improvement over the SE flash.

now once they flash it and i buy pipes afterwards and set the pc3 to work wit just the pipes would it be ok?

The new ECM flash from Harley will cover the factory SE 103 upgrade, and the motor company recently released a flash to cover their SE slipon mufflers and screamin' eagle intake.

Power Commander is really the way to go IMO, and not just on Harley's. I know guys running these on Yamaha and other EFI motorcycles and they all swear by them. What I like about the PCIII is not only do they have a wide variety of maps available, but you can tweak the basic fuel and timing settings right on the device. Plus there are always custom maps coming out.

I can't speak for your dealer, but I know the techs at my local Harley dealership are installing power commanders on new 07 motorcycles without sweatin people about warranties and EPA crap. They probably wouldn't want that advertised so I won't mention their name. If a dealership wants your business they will keep you happy, otherwise go find an independent shop or do it yourself... plenty of people here who can help you through it.

ok but what i want to know is if i take the pcIII map made for vance and hines pipes with the stock ecm would that still be safe due to teh stock ecm being re flashed
