I think a lot of "burning rubber" in these trucks depends on altitude, tires, gas, if the engine is broken in, weight, rear diff gears, road conditions, and probably a few other things I cant think of right now. Mainly I think this because I have had 2 f-150's and neither of them even chirped the tires at full throttle from a stop. the newer one has more get up and go, but it also has 3.73 gearing versus the former truck had 3.55. so if you get higher gears, you get more torque, and if you are at lower atltitude (I am around 7000 feet on average), you get more power, but less gas mileage, so dont expect very many people to say that they can do a burn out with just a programmer and E-fans unless all the factors are right, and you are in the right spot at the right time
, just my 2 cents
