It looks like I got a good launch but who knows what happened after that. Plus I was feeling a dead spot in the power band @ 3800-4000 rpm. My wideband was always in the mid 10's to 11.0.
This is horribly rich! I never saw anything above 11.2 A/F at WOT
Are you sure your WBO2 is calibrated well? I was surprised by how lean mine runs at WOT up to about 3500 RPMs. It's damn near stoich, then it drops into the 12's.

Long story. But started with just a base kit. 3 of the turbos were upgrades. And the other were from bad tunes. It was fully built with a six speed swap by the end. Here is a old, really old Vid of my frist ever dyno. This was not my 600hp pull it took another 1.5 yrs to get to that point. http://www.youtube.com/watch?v=1sZlv...elated&search=

Where did you have yours located? From some pics you posted it looks like in the rear of the exhaust. Mines about 10" from the primary cats on both sides. And with two they were reading both really close. I don't think they were that far off. One of the sensors is brand new.

You're correct, mine was in the rear eventually, but I started out with it in the OEM spot for one of the secondary O2s. I guess the cats probably made about .5 difference in the reading.
