maybe consider the zippers thundermax. it may not be listed yet, but john at zippers hooked me up with one two weeks ago for my 2006 dyna.
I did a short review and it seems the kit completely disables the O2 sensors, which may just have been the coolest part of the new ECU units. I guess we'll have to wait till the SERT is updated for this support.We have been shipping this unit for a bit over a week. You can
