yes steve, ya have to increase the line pressure on the tranny or it burns up ASAP, but the gadget to do this is only like $100 or $150 or so, and i think its easy to install on the dodge.
talked to my bud and he said that the dodge,bully dog and banks chips are the way to go, banks makes a kit w/the following:
*performance chip
*line pressure regulator for tranny (if its an auto)
*4" exhaust/tail pipe and muffler
*K&N airfilter system
*differnt springs for the turbo waiste gate to increase boost, ya just change the stock springs out and replace w/the new ones, looks easy, good idea ya dont have to replace the whole blower which is high $$
w/these mods they went to like 300+HP and 700+ ft lbs of torque at the rear wheels on a '01 3/4 ton dodge w/the cummins, and the kit was like 2K or so, now that is REAL improvement there, imho, 700 ft lbls of torque would be something to experience and would sure pull a trailor, i bet, lol
ya can also get nitrous injection and PROPANE injection, of all things, i won a 6 pack bet on the propane, it works like nitrous on 4 stroke engines somehow or another, but ya get a BIG boost w/that, and ya can also then add the nitrous also, put ALL this stuff on and it'd outrun my vette maybe.
