the PC3 does not use wide band, I think the PC5 does, for the money and ease of not having to weld in 02 bungs, I would go for the PC3, especially if your not planning on too much more as far as engine build goes. the PC3 is prob your best bet for the money. Super easy to install and map too man. give Jamie a call @ Fuel Moto - he can email custom maps when you get the PC for what A/C and pipes you have, or Dr. V-twin - ( DOC, you sell Power Commanders??) .

 

yeah! i sure bet they are very loud!
