My neighbor and friend just bought a 97 2500 5-speed. He is already quizzing me about how to get more power out of it. I have a 24v so I just told him to free up the intake and exhaust, get gauges and I would ask here what you fellows thought it would take to get him up around 325-350. He tows regularly about 12,000 lbs. and is not looking for EGT problems.
