Second, I've got PCIII's on every single fuel injected bike I have now or have ever owned. That makes 6 in the garage right this second and I've never had one fail.
I have had at least 5 bikes now with PCIII's and zero problems. Plus, after a custom map, it is amazing how much better the bike runs in all situations. I think I have gotten far more benefit from the daily running improvements than the outright performance, given the percentage of time I use each of those.
