Between the performance air filters, exhaust and the power commander, the power commander was by far the easiest of the 3 to install on my 06 Ducati 999. Downloading the fuel map was easy too. I hope I picked the right one. Still pretty cold here in PA, hoping to have it Dyno'd to see if I got the mapping right and to see if there were any performace gains. The Superstore had the best price I could find, plus free shipping.
