it may be me, but i seen too many people bolt on things like superchargers on stock engines and cause premature death of the engine. by all means im not tryin to discourage him from doing what will probably be fine, but there are always tradeoffs for more power. he just needs to understand the known and possible consequences of what he is proposing. hate to see a 08 with a blown motor, or not wanting to be driven becuase of poor gas mileage.
i guess its just a side effect of me for the longest time just doin what the customer asked as far as lift, tires, engine mod's.
honestly, if he just wanted a bit more umph from his 3.0, the way to get it done without warranty issues and sacraficing reliability would be a gear change, id be curious to find out what kind of gears his truck has, and whether its a auto or manual....
