I question about this Yosh box adjustment? I have a 650 with Staintune pipe. Have others done this with the 650 or is it mostly the 1000 that need to be tweaked richer from the factory setup?SemperVee said:For a one shot deal the dealer can Yosh box it in a manner of minutes for .5 labor. A PC will cost $300 and you need to install the software and maps via your PC.
A yosh box is very simple with a broad stroke.
The power commander is "Surgical" in its methodology and should be used in conjunction with a dyno, otherwise loading the map in is "Seat of the pants" tuning.
