Regarding my Power Commander III, I also bought the "Dual Map" switch which mounts on the left handlebar and lets me swap between the "standard" map that just smooths out the fuel flow across the rev range, and the "fun" map which gives a big boost to mid-range power, but does cost about 25% of my fuel economy!
There's now also the Power Commander FC which is simpler and cheaper, see https://dynojet.co.uk/collections/power-commander-fc
