I just finished installing a wideband O2 meter. That is the good part. The bad part is that the predator tune (r50b) is causing a lean condition. It is not bad enough to cause detonation in my case but it was leaner than I would like. At 3000rpm WOT the a/f was 15 it dropped to 14.5 by 3700rpm and finally made it to 13.5-13.7 by 4500rpm.
I installed the factory HP tune (without making tuning changes) and the a/f is a nice steady 13.5 from 3K up (sometimes it drops to 13).
FYI wideband O2 kicks arse
