    A few dealers say no you don't but the mixture is lean from the factory because of EPA regs and adding exhaust does lean it out some more but the addition of the stage 1 will definitely go over the line and need more fuel. I use the TFI to richen it up even with just mufflers and they run better. Your 06 doesn't have the 02 sensors to self adjust so I would say to add some fuel.
