For the money, to me, it just ain't worth it. It's a truck, the air-gap is pretty much a single plane intake, with a small plenum, so, you lose some low end torque, which is counter productive in a 6000 pound truck..... but, you gain in the mid, and upper RPM range. So, if you are building a mud truck, yeah, that'd work... otherwise... well, not so much.

Where you get the throttle body doesn't really matter. They come in various calibers, and folks have had good things to say about the 50mm guys. I don't know that going any larger really gets you anything. The 50mm will give you better off the line throttle response, which is a plus.

If you don't have headers yet, I think that would actually be the next improvement I went for. Lets the engine breath a bit better. (which means..... more power.....) Shorties are an improvement over the stock manifolds, long tubes can get you more power across the RPM range, but, can be complicated to install. Especially if you have to keep your cat.

Use GOOD gaskets for them though. Remflex Dead soft copper, or aluminum. Install 'em once, forget about 'em. No leaks.

This will certainly enhance your stop light performance, however, upgrading the gears isn't cheap, especially on a 2nd gen Ram 1500. If the differentials were Dana 60s, you can find good used gearsets pretty cheap, since the gears are strong and quite plentiful.
