You're probably right. I've never looked at the flow pattern on a fuel injected V8 through a tuner....hell...this car was my first modified Injected V6.
I'm not going to argue about what I don't know...I'm gonna have to study this subject. It would only make sense to actually have to use more fuel for more cylinders...and the M112 moving more air.
I still have a little bit of the old school carb in me I guess.
