I'm new to the board, and I personally don't own a cummins just yet. However my younger brother got a 94 5 speed last year and we have been slowly upgrading it. He uses it mainly for personal transportation, however, everyonce in a while it will have a boat or car trailor hooked behind it.
mods so far
4 inch mbrp, #8 plate, and cold air box, and of course gauges

My question is we're looking into taking the next step, I have a set of 3k governor springs waiting to be installed, and was wondering about injector- turbo upgrades, i have about 1500 to play around with and have a goal of around 400hp with out sacrificing driviability (with or without a trailor) and fuel economy. thanks...... DTR is a great website!
