that's right while on the dyno the guys from bullydog put a a fms premium box on my truck for a comparison. peak the comp only made 12 hp more but @ 2000 look at the difference!!! now i know the comp has a timing module but's it's damn near half the price of the bluebox. the bluebox was cool don't get me wrong. it has lots of gadgets and buttons. these runs were made within minutes of each other. the blue box was set at 63% fueling and the comp on 5-5.
