What did your friend test that carb against? Just curious.
And I've BTDT with MFI even to the point of developing my own barrel valves and a good 2x4 set up will blow its doors off.
Stack injectors, unless you can throw a pop can down the stacks run out of air very quickly, and it's damn near impossible to get rid of enough fuel to keep the fuel curve anywhere near close to half assed good.
