Power Commander 5 and Dyno Tune

[iamheero_imp]

Hey all,

Just got my bike back from a valve adjustment (forgot to ask for clearances) and dyno tune. When I bought my bike it had a Pipemasters 4-into-4 catless exhaust system, I also discovered that the previous owner put a K&N filter in there. I installed the Power Commander 5 myself before I handed my bike over to them, it's a very simple install if you can get the tank off.

Obviously these numbers are not a great absolute reference as each run is going to give you slightly different numbers based on what kind of dyno you're using, ambient temp and humidity, and the tuner's setup. That said, these guys have a very good reputation and I thought it would be of some interest to someone, surely. My 'before' figures are also not a good 'stock' reference, since it had a basic map on the PCV for the '17EX already and some airflow mods, but hey.

It's not a huge difference by any means, but feels slightly peppier and runs smooth as ever, if not slightly more smooth. I noticed a dip in the butt-dyno power levels around 3500rpm before the power commander install which as you can see is clearly gone now. The thing that I liked the most was the super flat torque curve, the CB has such a nice little engine.
