I have a 99 Chevy Silverado with a v6 and would like to get more horsepower out of the motor. The ONLY time this truck is used is for towing our boat. The total load that the truck is pulling is roughly 3500 pounds but there is a LOT of wind drag in addition to that. I live in a flat area. The only hills are overpasses :)
It does OK if I am running 60 mph but.... well you know. Plus I'll bet that I'd get better gas mileage with more HP on it. So........
What could I do to add more HP? PLEASE be specific! Better air filter? Computer chip (Really specific here please)?
