The Final Word
The results speak for themselves. We gained 113 hp and 80 lb-ft of torque over the stock numbers and, boy, can you feel it. Driving the monster home was quite an eye-opening experience, and we will have to get used to having this much power in a truck this high off the ground. One thing we will report: This truck does one hell of a nice burnout now, and our poor Terra Grapplers are soon to be bald.
