I've got an 06 LLY Dually whose purpose in life is to pull heavy 5th wheel. By heavy, I mean slightly over GM factory specs.

Loaded, I could use a little more umph getting on the ramps and tackling the bigger hills.

I have a Hypertech and used it on a short trip. I liked the power but not happy about the soot all over the side of my trailer. I figure that's wasted fuel and its aggravating to get that black stuff off.

I ran the regular Juice on my '01 and liked it fairly well.

I'm looking for a mild tune that's clean and cool, maybe to LBZ specs or so. EFI Live looks really good but it seems like an overkill for what I want to do.

Can any of you guys that tow heavy tell me your experiences and recommedations.

I know these questions have been asked over and over so thanks in advanced for your patience.
