 Great all around truck with great towing power and torque. I added a k&n intake. E3 spark plugs. And drilled and slotted ebc rotors with ceramic pads. I have to say for some small bolt on mods. The truck performs like a sports car and pushes over 300 hp. With the truck breathing and sparking so well I have been getting 21 mpg city and 27 highway. I also use the high octane fuel the owners manual suggests. Nothing under 91 octane. You can use 87 in a pinch but if the folks who designed the engine ask for the good stuff. Its for a reason. Use it!
