Okay, so I have an 04 lb7. only thing done to it is some ghetto straight pipe from the guy before me where the pipe changes sizes like three times. that junks about to get replaced with mbrp turbo back exhause. but my real probelm is what to do on a programmer. I dont do much heavy pulling and my truck is my daily driver. I dont get on it all the time, but I would be lying if i said I never did. All of my friends have efi live, but I don't want something that much. this is my first diesel and i want to keep it simple. I am mainly looking for mpg, a little power, and a little smoke. I know thats like all three programmers do, and its hard to get all in one, but what do you guys think? I want something fairly easy on my truck that wont rape my tranny. THANKS A LOT!
