I would like to increase the horse power of my stock 02 dodge cummins diesel. I would like to get to the 300 hp range and add 40-45 ft lb of torque. There are many brands of computer boxes, edge, tst, bd, banks, and the list goes on. My question are they all good or are some better than others?? My rational for wanting this added hp is I pull a 24 ft 5th wheel with a boat tagged on behind. My truck is automatic and I am constantly shifting in and out of overdrive at every little grade, get my drift? I would like to be able to adjust the power as needed. I am open to all suggestions.
