I have a stock 06 LBZ WITH 150K miles, the only up grade is the K&N cold air kit. I plan on leaving it stock as I use it for work towing 4000-7000 pounds 6 days a week, 400-500 miles a week. But I would like a tuner for towing power and better fuel economy. A buddy runs a Banks and swears by it another friend says do with the edge. I'm new to the Duramax, it has plenty of power just looking for a little better fuel mileage and perfomance with out messing with the life of the truck. My last truck was a 98 12V Cummins, it would of run forever but didn't fit my needs and even in a 2wd it still rode like a tank. 185hp 440ft just wasn't me I'm a chevy guy. So tuners are new to me, lets hear what you think, remember I'm planning on keeping everything stock.
Thanks in advance.
