What DME chip are you using, stock?

I'm assuming you are not running the narrowband o2 sensor since you state only 2 bungs and both have wideband sensors for logging.

AFR during city driving looks very lean. Cruise AFR looks normalish, maybe a little lean. WOT looks to be expected.

What is the history on the air flow meter (AFM)? Is it the same one that was on the car prior to rebuild? Any indication it was ever opened up previously? When i bought my car, i found the clock spring in the AFM was adjusted to make the car run lean, no doubt to get it to pass emissions. Its possible your rebuild fixed a few issues a misadjusted AFM was hiding, so now the car is running leaner as a result. At WOT the car defaults to a preset fuel map which looks to be reflected in your datalog.

Interesting you are getting such mad mileage. Is their any other indication of this? Rich smelling exhaust? Sooty tail pipe / bumper? Smoke from tailpipe during idle / accelerating?

How was fuel pressure checked? Does fuel pressure match the normal spec at idle? (i forgot what it is). How about when you pull the vacuum line off?
