[QUOTE="Mwilbur516, post: 263658, member: 784"] Bill, the Atlas 80 tune is awesome. My fuel mileage is back and the midrange pull is amazing. I am really thinking about the Hercules tune now. The original FICM tune was great, but the Atlas 80 blows it out of the water. I've changed nothing since you reprogrammed the FICM the other day and my fuel mileage has crept back to around 17mpg (hand calculated several times). My towing is usually limited to 2-6k, but 10-11k does happen. I think I want to try the Hercules tune. I really believe I would be OK. The thought of more power and fuel mileage just keeps pushing me towards the Hercules. [/QUOTE]
