I am asking this question for my brother who lives in Calif, and needs your advise regarding Power Chips. He has a 1999 TD, AT, with 3. 55 rear end. It's a 3/4 ton, long bed, quad cab, 4X4, with 53,000 miles on it. He just put a new Lance Camper on the truck and would like a little more power in general. He is thinking about the Hypertech Power Programmer III. Whats your opinion? His truck is stock and runs great. All he wants is more power without harming the trans etc. Any other programmers to consider?
