What did your AFR look like?

I'm guessing that you were running your injectors wide open at the top end.

(17*4)/.45=151.1 crank HP

Something isn't adding up. With drivetrain loss you'd be looking at 120WHP.

When did you switch to 42's?

I wonder if the 98+ Contour's can really bump the fuel pump voltage to avoid a lean situation. BUT... You'd be at WOT, open loop, so it wouldn't be reading your O2 sensors at that point.
