NOTES:

Just for shits, I hooked up a PC3r with base map and discovered a loss of 7.5HP. Guy said the fact that bike is a 32bit processor and the PC3 is a 16bit processor makes a difference. The bike's timing information can't be read fast enough to process properly (or somthing like that), so it's difficult to get any more power into my stock bike using the base map unless he spends many hours figuring out the discrepancy. Could this be the case? I would conclude that on a stock or flange-on bike, a PC3r with base map for is shit, so don't use it or you'll lose 7.5 HP.

He did show me results for a full Muzzy with PC3r, and downloaded map from DynoJet that had significant gains. Then, he was able to add 5.5 HP up top after tweeking that DynoJet map.

My next step is to decide on a full system, Muzzy or Akropovich, and toss that fricken stock exhaust with flange in the trash.

"DYNO:

Not to worry - that particular dyno will give you "low" numbers like that. You'd probably get right around 140-143 horses on that dyno with a bone-stock 12R. Interesting to note that your peak horsepower moved up to 10,500 rpm with the addition of the flange-on muffler. Without the flange-on your peak horsepower would have been around 9,500-9,700 rpm. Just goes to show how much Kawasaki restricted the U.S. and Canadian models with the mufflers we got from the factory!! <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/smile.gif ALT="
