FYI Rafiki:
If you ever to get a full system or would like a Dyno tune... find someone who knows how to tune using the Yosh Box (Ryan Gill does, was/is he at Pro6? Don't know for sure). But he can tune it using the Yosh Box and do an awesome job for you. It would be cheaper than spending the $400-$500 for a Bazazz or PC with Autotune (basically making changes on the ECU and don't need fuel management hardware). So if you ever find a deal on a Yoshimura system, that's a good cost effective way to get performance.
I actually still have the ecu from my 07 gsxr 600 that Ryan Gill tuned and dyno'd for me in 2009 at Rider's Choice. Don't know if you'd be interested in buying from me, but i'll put it up for sale since I have no use for it anymore.
