Oh that was a much shorter and easier answer than mine....I'm a complex person, I know this.
Good thing I'm subbed, FO really knows how to bring simplicity into this world, whereas before we were limited to certain engine sizes due to stock tbi flows, injector sizes, etc etc etc. Now the fuel system issue(air & fuel flow rate) is pretty much gone, which was the major bottleneck when choosing to go oversize. Also, a carb(when tuned correctly) won't get just horrible gas mileage, all depends on your foot, but your foot also plays a role in tbi, so that reason is null.
In short, thanks a bunch buddy, this was extremely helpful, and I believe it should become a sticky!
