I don't have a PC5,
but the DoBeck unit is on the fly adjustable and smaller
than the PC3 with no cd or canned tune to mess with.
Real simple to operate, its plug an play and comes ready to rocknroll.
Order one for a rocketIII, plug it into the throttlebodies and try it out.
It's about the same size as a creditcard. A little thicker, but about the same size.
The guy that invented the PowerCommander and sold it to DynoJet, is DoBeck.
He knows their unit pretty good and has a superior unit for sale at about 1/2 the cost.
Significant discount for veterans too.
At least I like it, and I'm having WAY better luck with it than the PC3.
