I’m still getting to know my XX. The BB I purchased came with a Dynojet Power Commander III. So I did some research on the EFI control and have found I can upgrade to a Power Commander V, however, the new unit does not have the individual Low Mid and Hi manual fuel adjustments that the III has. I think this is a cool bonus feature. There are some limitations to the PC III like limited software support due to the age of the unit but the software and electrical cords are still available through Dynojet....Should I upgrade to the PC 5 or not?
