Hey guys, My name is Billy and I'm a combat engineer in the army stationed in white sands, new mexico. Im currently deployed in Afghanistan and will be coming home next month. I just bought a 2008 chevy duramax 2500. This is my first diesel. Im looking for the best chip to put in it and would appreciate some great feedback. So far ive looked at the Edge juice w/ attitude and the superchips flashpaq. I don't think I want one on the fly because I ont want it to be able to pop out of the mode I set it in. My main concern is fuel economy. I plan to add down pipe exhaust and cold air intake as well. Let me know what you think. Thanks.
