I've been considering one for my bike. I'd need a slightly different tune than you since I'd have stock filter and a LV pipe + altitude where I live is 5,000 ft or so.
I am interseted in your opinion and findings on how it works and improves things.
Why not just pay the money for a real dyno tune with sniffer? I know it is expensive but with the PCV it can really be dialed in by gear, etc.
