Don, thanks for the detail and I really appreciate where you are coming from. I like the auto tune feature as well and was the only reason for considering the Thundermax again, but I believe the PC will have to come out with something similar in time. The advantage in my mind with the PC unit is it is an add on to the factory ECM so should it crap out when you are in the middle of nowhere (just my luck), the bike will still run, albeit lean, to the nearest HD dealer who stock PC's.
One of the big advantages Zipper's has in my mind is that they produce a package of matched components that have been tested so you know about what kind of performance to expect before you put down your money. With the MOCO it seems like a crap shoot when you get beyond the Stage 1 & 2 kits and I know many people who spent a lot of money thinking they were going to get big power/torque gains using various SE components and didn't. My intent was to pull the whole motor and send to them, have them rebuild including the Timken bearing conversion and return to me as an assembled/warranteed motor. My concern is if they did an "average" job on the heads, how would the rest of the motor come out if they did all that work?
I think most all on this site who have purchased Zipper's bolt on performance mods (i.e. 575 cams) have been satisfied, at least I am. I would be interested in hearing from others on whether they had the same experience as you, but like you, I feel that work never should have left their shop, whether it affects the performance or not. It's a quality thing for me.
