It's barely needed on a stock LT1 as it is (the car has a MAF), and I'll be
using larger injectors for the larger motor.

Que? Without the FMU right now with stock programming the 02 values are low
800s. All I need to do is get it up to about 880mv, and I don't think I
believe there's not enough capacity in the stock fuel system.
