I'm a new member and am looking for information on how to get more power and better fuel mileage while pulling a 34' fifth wheel trailer. I have a 2006 F350 super duty with a 6.0 V8 that I have been happy with it, but when the warranty runs out I want to install something that will increase power and fuel economy. Thanking whoever can help with things that they may have done to strenghten their Ford super duty
