hi everyone, great site. im the proud owner of a 2009 xtx.
just started doing some simple mods, will put pics up soon.
i have fitted a k&n air filter and will be purchasing an exhaust system soon.
would i need a power commander?

and to

If you just fit a stantard K&N filter which replaces the oem, you won't need a power commander nor any other fuelling device, not even if you change the exausts. You will need some sort of fuelling device if you get a DNA stage 2 filter which is the one that gives you more HP, the K&N will not make a lot of difference in performance.
