Welcome 930shark,
I can't say enough about the Heffner Pully and tune that I have installed in my Heritage. Customer service was the main thing I was looking for when shopping for a packaged set of tunes, and I was not disappointed in Jason Heffner's customer service. He supplies a 91, 93 and 100 octane tunes in a SCT device. Very easy to use, even for a dunderhead like me. If you ever have a problem, or want to customize your tune, he is available to help you by phone. The only problem that I encountered was a lack of a WARNING label after the tune was installed. I immediately went out onto the freeway and swapped ends. Didn't hit anything but soiled myself. Immediately recognized that with the additional power, the stock Goodyear tires, although very good, could not hold the extra torque and power that the engine now delivered. So, remember to include into the price of the pully and tune, a new set of grippier tires. Have fun.
