I do have a power commander installed, running a blended map. It does pull harder than before but I was running stock map prior with stock exhaust. Also stink is less, though it wasn't terrible before.
Not sure how it will be, if anything should lean it out a bit. Stock is very rich hence the stink. Read your plugs, also you'll notice throttle stutter if its to lean. If you het a PC I got a nice map, there are also a lot put there from google. Good luck, let me know if you have any questions.
