I purchased an 06 3500 a couple of moths ago and it came the AFE air box, banks ram air and a 5in turbo back exhaust. I just purchased the edge with attitude and have not installed it yet. My question is since I am not running a cat I assume I will not get any EGT readings??? Will I need to get a seperate gauge for that. I recieved PM from a guy about any problems I may have without runnning a cat on an 06. I have not heard anything about that, has anyone else??
