I've got an '01 7.3 w/ 160,000 miles on it. I've added an AFE ProGuard Stage 2 intake and a 4" turbo back Magnaflow. Over all added about 2 MPG and a little more get up an go. Now that full is over 3.50/gal., I'm thinking of adding a programmer, either a Flashpaq or a Cortex. I've recently purchased a travel trailer and do OK, but the extra HP gains would be nice while towing and the "enocomy" mode for everyday...?
Comments, suggestions......
Thanks in advance
