4.8 is a good motor. With full bolt ons cam and some head work that truck will be killing some diesels

Wanna go fast at the track or on the street (not the Autobahn) then please do get rid of the 4.8 in favor of a 6.0 or bigger.

just trying to emphasize how important a tune is, lol, he was wanting to go with a handheld and is against motor swaps.or save up & do it all at once... that'll save ya $50 or so in PCM shipping
Keep in mind he is also in a ext cab 4x4 isnt he?
The tune, cam, stall, built tranny is all needed.... he should seriously look into a Supercharger or n2o to get that big pig off the line hard. The tq is what he is probably missing right now.

the OP doesn't want to listen to us anyways. ECSB 4X4 needs a power adder, period.
Honestly if he does all he can to a 4.8 with no power adder in a truck of that size and weight he will be walking into a gun fight with a ice pick when it comes to a modded turbo desiel.
