2007 Ford F-150 Herculiner - Rolling Thunder
Way down at 2,300 rpm, torque jumps by a butt-crushing 221 lb-ft, to more than double its factory output. Can you say "throttle response?" Horsepower isn't forgotten either, with an extra 199 or so on tap at 5,200 revs. And, as you can see from the dyno charts, these increases aren't peaky or limited to small rev ranges. The curves are radically up right across the board. This thing should haul, uh, just about anything. View Related Article
