Whats the deal. In the summer my truck was quick but in the fall with the low temps my truck flys. Fo those that dont know I have a 05 f150 Supercrew with the roush intercooled supercharger. Why the night and day difference? Are supercharged Bonnevilles much quicker in the cold weather?My intercooler is behine the radiater so I cant see it getting that much more cool air?
