Ok, so it's not GM specific: I have a 2000 Dodge Ram 2500 4x4 with the 24 valve Cummins, 48RE, and 3.54 ring and pinions. I just bought a Banks Big Hoss Diesel Programmer from Schied Diesel. I wasn't gonna get one until I could afford it, but they had it on clearance for $150 less than normal retail. Does anyone have any experience with this product? I'm anxious to know what to expect.
