What's next? that seams the to be the Question. I have an Early 04 Cummins HO, 305/555 motor. NV5600 6 speed, 4.10 gears, Hell bent leveling kit, 315/70 r17 Duratracs, Regular cab. mods that I have now. AFE mega Cannon, MBRP 4" stainless Exhaust, Smarty pod TNT-R, Valair 3600 Duel Disc clutch, Gauges, EGT, Boost, Fuel, SR Mia, have Air dog 165 just not on truck yet, soon. so what should I do next? I Drive this truck on Weekends and on trips looking for 500 to 600hp at rear tires, Going to some shows this summer so going to be looking for Parts. Was thinking Head studs, And while there getting Valve Springs, then while apart thinking of doing injectors, but Don't have the cash for all three. or should I get a bag of parts for CP3 and go for a turbo. Just can not decide. Any suggestions on what to do and why Will help. Truck has 73000 Miles on it. Thanks in advance
