I bought a 94 Ram 2500 with a 5.9l as I needed something bigger. Its mostly a parts getter/tow rig. We pulled a trailer with some tools this weekend and while it did alright I want more power (who doesnt?) So my plan was to pull the heads off and have hard seats put in and a valve job, basically a refresh, do a cam, cold air intake, headers and exhaust. At what point do I need to modify the computer and is modifying the computer on a 94 even possible? My desktop dyno says the changes Im going to make are gonna be worth between 50 and 60 hp and the same in torque. Two cams Im looking at, both are Comp. The bigger cam is 210/220 @ .050, .480/.512 lift, 112 LSA. The smaller is 199/206 @ .050, .480/.480 lift, 112 LSA. Help is appreciated!
