wbO2 + datalogging, very lean? JAK?

Put the Innovate Motorsports wideband O2 sensor into the upper O2 boss on the cast turbo elbow. The nbO2 sensor for the car is in the lower O2 boss.
The datalogger is way cool. Sadly I am running way lean. From a running start in 2nd, WOT max boost of 15psi-ish, the shift to 3rd hold WOT until near reav limit.
a/f starts out steady 14.0, then at 1.75 secs drops to 11.5, bounces to 11.0 then at 2.75 secs is at 18.9 which tappers to 14.0 all the way to 7 seconds. I'll assume this is the 2nd gear pull then shift (11.5 reading).
What scares me is that I start out in 3rd gear at 19 a/f ratio which tapers to stoic 14.0 until I shift again.
Car: 1985 900t sedan, K&N shielded under hood, later IC pipes, 3.0fpr, 24# ford injectors, MSS cat back, rebuilt head, rebuilt T3 with water/oil, timing it 20/10 with mod. canister, AMM adjusted to 14 a/f at idle..
Anyone have any suggestions? I will be logging RPM and boost probably within the month.
JAK, you had any fun with your wbO2 yet?
