I have an 03V with the powercommander and aftermarket pipes. HD says that if I go with the 28T front pulley, the PC will not work well because they have to download a map, but not thru the PC..
HD says its hit or miss
:bs: The PCIIIR will work the same, it's just that you need to recalibrate the speedo for the 7% difference. It can either be done with a flash or an aftermarket speedo correction module. Alternatively you can get Race Tuner that allows for anything PCIIIR does + more and also has an option to correct the speedo.
