I had a chance to go out for a test drive this past weekend, and could not be
more pleased with the results. I still need to get the tune dialed in, and had
things setup intentionally on the rich/conservative side, but did get on the
throttle a bit. It pulled nicely - gave it 80% throttle and ran it up to 4400RPM.
Indicated boost was 7PSI and rising. AFRs were in the mid 11's, and injector
duty cycle was passing 85%, which is no surprise since I still have my 42#/hr
units installed.

Next order of business is to order up a set of suitable sized injectors. I'm leaning
towards 80#/hr just to have plenty of margin. I like the ones sold by Ford
Performance parts as they have full datasheets available, making them
especially easy to calibrate.

New in-tank fuel pump is also on the way - I settled on the TI Automotive
F90000285, which ought to be plenty for my goals.

More work to do, but very happy with the direction things are headed.
