I have been told that the stock tc is very sloppy, and a good aftermarket one even at the stock stall would see a nice improvement off the line.
I have also heard this, hence the reason I'd like to upgrade it. Not to mention its not terribly expensive.

Don't go cheap..... or you will end up with the same issues. An 80 dollar torque converter is NOT an upgrade.....

If I went just a hair higher what would that do, like in the low 2xxx's.

Haha well no, I don't believe in that! One thing I don't go cheap on is my truck! But by not overly expensive I mean less than 500ish. I'd say one in that price range would be alright huh?

Yes,

Wayne at APS Percision makes good torque converters, as does Martin Saine, and I've also heard good things about the PATC converter.

Be careful on overdoing your stall speed. Higher stall= more heat for the trans to deal with. You need to match the stall to your engine's power band. A good rule of thumb is to go with a stall that is 400-500rpms lower than the start of the power curve. If you haven't modified your truck that much, stock stall is probably optimal. If you've done some more extensive modifications, and we're talking heads and cam here, you really need to dyno your truck to find out where that sweet spot starts.

Keep in mind too, that a heavy truck tends to "stall" higher than in a light race car, so a 2400rpm stall converter can act more like a 2600 or even 2800rpm converter.

honestly, if you have your mind set on really modding your rig, a converter should be one of the last mods you do, to avoid having to do it twice.

Yes that indeed does make sense. I'm looking at either turboing or supercharging my truck, 1.7 rr's, and probably a new intake manifold. Also maybe a shift kit. Also a tranny, oil, and powersteering cooler. I was going to go with dual electric fans but I was worried how they would handle with the towing. And after everythings done I guess that's when I should add the tc.

We have several folks that tow here, with electric fans, and they LOVE them, as they get air flow when they are backing up their heavy trailers. If you get mean enough fans, it won't be an issue.

Why would you go in reverse while towing?
