I have a PC II on my 2000 'busa and I've searched everywhere for a map to suit my needs. I have a full Akropovic exhaust and a K&N airfilter. I do not have the airbox mod. The map on the power commander site does have a map for my exhaust, but for a stock airfilter. Will setting this map create a noticable difference? Or does somebody have a well tuned map for this setup? Another question I have is, is that if I upgraded to a PC III, is it directly plug and play like my PC II? As in, all I would have to do is follow back the wire to the ECU and just easily switch out the power commanders? If so, how long of a job is it? Or is a PC III even worth it for my non complicated setup? ??? Help a fellow noob-brother out! Thanks!
