I was questioning for a while whether or not to pick up a programmer for my tahoe. I picked this up with the intention of adjusting for my larger tires and doing the basic tune for premium gas. I did notice some power gains as well as a mild boost in gas mileage. I do not know exact numbers but I would guess it helped to add around 2mpg..I am averaging 19.7 overall! I ended up adjusting the transmission firmness as well which ended up being super noticeable and beneficial...I never realized my transmission was so soft before I changed it and now it shifts like a sports car (and its a tahoe!). I got this for a great price while it was on sale, so I purchased it on impulse. It ended up being one of the best impulse buys I have made. I strongly recommend grabbing one of these if you are looking to get a bit more out of your truck and give it some life.
