This is a response for the OP, if he is still out there. Not to start something, just another way of looking at it.
You took the time to learn how to work on carbs. There are plenty of people here and elsewhere who have problems with carbs. Learning to tune one or the other is no different other than the way tuning is accomplished. The theory is fundamentally the same: get the right amount of fuel into the engine at the right time. Carb or EFI is fairly difficult to dial in for day in day out driving. Max output in a very narrow RPM range is pretty easy with either.
It would be a stretch to say that a low-end carb or carb rebuild is as costly as getting into tuning EFI, but when you start talking about higher end carbs, it is every bit the same cost, if not less, to tune EFI than to swap in a carb.
As has been stated, when you own the truck, it is yours to do as you wish. Take all the advice given, apply it to your situation, and make your own decision!
