I COMPLETELY DISAGREE!!! The pcIII is probably the best mod you can do 1st. Even running it with the re-tuned map for a completely stock bike will make it run a hell of alot better. For $270 I say get the pcIII then exhaust. You'll thank me later. Remember though, your not gonna pick up a ton of hp with any mod for these bikes unless you do motor work. With the pcIII its more drivability your looking for. You'll gain alittle power, but the thing is gonna drive a hell of alot better.well there would be no point in really doing the Power commander first as I would just have to get the thing re-tuned once I install the exhaust right?
Either way, PCIII and full exhaust is a pricey first mod! Gotta love it though!
