I am fortunate that a good friend of mine owns a dyno. We spent some time with my 04 ZX10 and tried several different "off-the-shelf" maps from teh powercommander website.
My bike has a muzzy slip-on, BMC air filter, secondaries removed, air injection blocked, and exhaust valve disabled. All stock otherwise.
We found that the PC map which was designated for an all stock bike (stock exhaust and stock air filter) gave us the best AFR (12.8:1) and the smoothest power curve.
The PC map which was designated for a slip-on and BMC filter was terrible. It yielded a very rich WOT AFR, and was way too lean at part throttle. The bike did not run as well with their recommended map.
Just some food for thought, and more reason to get a real dyno tune.
