Question, which box is turning out to be the best for the new 600 ft lbs. 04.5 cummins? I'm fairly happy with the Edge 125 hp box on my 03 Duramax, but am unfamiliar with what is working for the Dodges..


Thanks

The mild box right now I believe is the Edge EZ. It's a pressure box.

The competition box is the TST POWERMAXCR™. 180 hp 550 Ft Lb Tq at the rear wheels TST (http://www.tstproducts.com/powermaxcr.htm)

BUTTTTTT..... trans.... turbo minimum if you plan on using it at it's higher levels.

Word is the auto trans won't take any more than th eEZ without upgrades.

Do big exhaust first unless you planon a turbo. In that case the exhuast must fit the new turbo.Edited by: hoot
