I have a stock 2008 Chevy LMM with 200,000 miles on it. We bought a 28ft camper that weights 7,000lbs. looking a good programer. Looking for help with towing and daily driver MPG's. Any info would be great.
Do you plan on doing emissions delete? (cat,DPF,EGR) If so EfiLive by one of the major vendors would serve you well. DSP5 will give you all you could ask for and then some.. Big gains in power and mileage,,
EFI live hands down, even if you are keeping emissions you can get emissions friendly tunes, the benefit will be much greater though if you delete the emissions and get it tuned accordingly.
