99 4x4 automatic cummins 2500 long bed with about 78k on it. not really doing any towing. maybe a few times a year. i do construction and sometimes have to carry heavy loads (i.e. sand, concrete, tiles...). what kind of power mods can i do without having to change out the tranny (or at least too soon)? right now im looking at the 275 injectors. also, would one of the update kits for the tranny be worthwhile? would it prevent having to have a new tranny put in? im new to all this and trying to establsih a starting point here. thanks.

You cant do shit without blwong the tranny....hell you cant even drive it :laughing:

ok....Do exhaust, Edge EZ chip, and BHAF and you will be set. Search the tow rig section there are some good threads on CUmmins there ;)

BHAF?
