I love shocking people with my 99 F350 7.3L. They seem to forget what a little torque breaking and about 750lb-ft do with a truck. I have bulldog 4 bank chip, big woof turbo upgrade, 4" downpipe with 4" exhaust, and thhe bullydog intake(along with a few other toys like and exhaust brake and such) and my best kill was two kids in a civic hatch. I was minding my own business and crept up a bit. I suppose they thought they were the proverbial shiznit because they started laughing their asses off and started revving their little toy. I torqued up and the rumble and whine of the ol powerstroke gave them a new expression. The light turned and of course they chirped the tires and tried to get away, I laid rubber for about 50 feet and passed them as I was laying strip, I let off a bit to get traction then burried it again. By the time I let off you could fit a stadium between us lol. We got to the next like and these twerps wouldn't even look at me lol.
