TB Spacers
I have read all sorts of things about TB spacers, and know for a fact that they work great on carb'd vehicles but how much of a mpg/hp increase do they give on EFI trucks, especially OBD II trucks?

I have heard none. There is no fuel to swirl with the air to atomize better. I am wondering it the added length of the intake track by adding the spacer would increase torque any though. Longer runners = more torque.
i ain't rite

if you listen to the people that sell them, tb spacers will give you up to and maybe even more than a 50 hp increase. if you talk to dyno owners and operators, they will tell you that tb spacers are just as effective as in the air intake tornadoes and fuel line magnets; the only thing they are good for, and do quite well, is make the wallets of buyers lighter, and make the wallets of the sellers heavier.
