To you Diesel guru's.
I purchased a '96 3500 auto with the Cummins Diesel and I would like some advise on performance up-grades. I will be using it primarily to tow a 28' enclosed car trailer with the occasional home owner run to the hardware store.
From stock, what would be the best order in minor modification to be done without greatly affecting reliability, drivability and fuel mileage? I've heard of sliding the fuel rail forward and i don't know what that means. I know next to nothing about Diesel engines so remember that when giving your answers.
What would be the mod's and in what order would you perform them in?
Thanks in advance.

I've had a 1995 3500 since new. When new it wouldn't pull my 26" trailer up a steep hill on the interstate over 58mph. After these mods It'll go 70+ up any hill pulling my loaded 32 tri-axle, 64 Belvedere and a slide in camper Gross weight is around 19500lbs

Then cut the front of the air box open as it's opening is to small, stock filter element seems to work fine. Turn the boost to 30-35 psi. Finally have the pump timing set to 16 degrees. Depending on how far you slide the plate it will smoke some. Fuel millage will not suffer. Performance will be night and day. Mines been like this for years. 190K no issues.
