I've always heard that HD stood for Hundred Dollars but the extra cost it takes just to upgrade your exhaust to get a little more sound is outrageous. I can just imagine the meeting between the HD engineers and the Department Heads..." Boss, I've got this idea to milk even more money out of our loyal customers... Really, how?....Well, lets make the bikes very quite and develope the electronics to be very difficult to adjust so we can charge them an absorbant amount of money for the nessasary tools to upgrade anything." What is the best/efficent and cost effective way to get around the need of the HD race tuner? I've read the many threads refer this but what is the down and dirty? The PC III or any of the other types other than the HD race tuner please.
