I tested the Pro Circuit full system with the Power Commander III with the mapping for that set-up. I was very happy with the results. Throttle response was greatly improved. The engine felt like it was a completely different from stock. Power was still very smooth. It felt as if there was a bunch more power available and you could lug the engine a bunch more if you wanted. I really think that in the dunes, this set-up will be awesome.
I did get an opportunity to open it up on a fire road. After I pulled away from my buddy on his YFZ, I asked to do a couple of drag runs so that I could post the results. He flat out refused! :angry: Even after some razzing, he refused to line it up with me. Needless to say, I don't have results. I do think that I would have him off the jump, but in a long run he would catch me.
If I can figure out how to add pics to this site, I'll do so. I've got some right after the install so everyone can see how things look clean.
