Hello, Im new to the forums here, and its great to find a place with such great info! I recently bought a 97 250HD extended cab that is completely stock. The truck has 70,000 miles on it. I plan on doing a fair amount of pulling with it as far as equipment and a travel trailer. I would like to tune it up a bit, but am pretty unsure where i need to start putting my time and money to get the best bang for the buck. Anybody have any suggestions? Thanks for your help!
