today i put the V&H pipes on , i used the power commander along with em, i tried map# m805-198 from the site and it didnt work , tech assistance said to use it as a starting point, i ended up using one from the user upload section #m805-vj038,, i plan on taken er in for a dyno tune this weekend at LAIDLAWS they are a power commander tuning center.. if you have a power commander make sure you enable the accelerator pump utility tool thats a free d/l from the site,, i set mine at 90% sensitivity 15% fuel deliverey and 20% rotation, it made a big difference, it's set according to the riders habits , so im sure i'll be changing it from the standard setting..
