It's like picking a lawyer out of the yellow pages. There are so many outfits selling tuners for Duramax trucks. I have a 2004.5 LLY and want to get better MPG towing a fifth wheel trailer. I don't care about more power, don't want to watch EGT's, don't want to increase the noise level.

Stock, I get 10.5 MPG actual at 62 MPH and no wind. I get 12+ at 55.

How to select a tuner for it?
