I have a 2000 GMC Sierra 1500 4x4. I am loooking to put a tuner in it and give it a little more performance. I know I probably won't get and MPG out of it since it has 6 inches of lift and 35 inch tires. I usually haul my boat and occasionally pull my horse trailer around with it. Any advice yall can give would be greatly appreciated.

Just call nelson performance and order a professional tune. You get lifetime updates for the price of shipping a new PCM round trip to San Antonio. Don't be surprised if you pick up a little fuel mileage, too.
