i havent read everything about the ssr, my friend has one in his commonrail and its not really that fast, my 04.5 has a bullydog powerpup, afe stage 2 intake, and straight pipe, and ive beaten trucks that he doesnt beat, maybe he doesnt have his tuned right? im not sure, i was just basing my question off of the idea that the smarty ssr isnt a crazy tune, i didnt realize it was as good as you are saying because his truck is the only one ive seen in person, and as i said, its not all that impressive. i wasnt trying to offend anyone by my ignorance, im a bit new to this whole computerized vehicle thing. my other trucks i have owned have been twelve valves and this is my first truck with a computer.
