My buddy has an 01 Cummins 4x4. Already has a good 4" turbo back exhaust and will have guages shortly but he would like to get a good box for some more power and also a little fuel mileage if possible. I am an IDI guy, so the Cummins is new to me, if you guys could point out some of the good ones, I would appreciate it. He is not going to upgrade his tranny, which is the 47re, so it needs to be a mild box or at least adjustable so he does not destroy his truck. He just had his lift pump replaced, so he "should" be good for a little while. It is his daily driver and weekend puller for his Jeep and trailer so it does get some towing use. Thanks for the help guys. Scotty
