Not sure who asked this, I find digest mode irritating. Anyway, if you
convert a carb intake to TBI, you will experience the same fuel pooling
issues for the most part because the fuel is still pre-runner. Minor
difference might occur because EFI is more precise than a system
affected by changes in motion (float bowl slosh, inertia on the valving,
idle circuits, etc).
For TPI, SFI & PFI, you'll find that you will make at least the same
torque, if not a little more, because the runners are still the same
length, diameter, etc, tuned for a specific RPM range for its max
torque, however you have then added more precise fuel metering, so
through a little fancy table editing, you can get a little more out of
it. Masters of the Code obviously would do better than a monkey with a
prom burner like myself :)
