Picked mine up for $12,800. With new pipes, intake/filter, programmer and under body armour it now owes me $15,500 ................................and worth every last cent. Oh and they go well with turbos on them so it should be right up your alley. $450 buys you the programmer which just plugs into the bikes ECU. Then you just visit the Power Commander website where you will find a list of tunes designed for your bike with just about every combo of mods, downloadable free of charge. In my case they didn't have one for my dual DMC pipes as they have just been released so I used one for the same set up with different dual pipes. Save for a couple of HP up top, the result was nearly identical to the custom tune graph I posted, aside from the AFR's being a bit on the lean side in parts. The programmer also provides the user with the option of fine tuning maps by playing around with the fuel tables throughout the rev range / throttle positions.
