Have any of you all tried a cover; get some of that air out of your beds. I had one on my old F1-50 before I traded and was so spoiled with having one that I purchased a tri-fold for my 2010 RAM Laramie. Running the same trip as I did with that Ford (04/5.4 Tri); I picked up 70 more mile on the Hwy before my light came on! Now that was holding around 75 and seeing 80 every so often. Tri-fold from Mustang close to 1000.00
Ready to start work on my (02) 5.9; 4X4. I got a K&N Cold air, headers, magna flows (6 months ago),fresh belt, and tune-up. I got some OEM drilled and slotted rotors for 20in wheels and higher from R1Concepts for 385.00; they do great work; I purchased some for the Ford and changed pads once in 4 1/2 years (everyday driving). I was also told about a tuning alternative instead of having to replace the chip. Also; if you have a cold air intake, you might want to get one of those sleeves for it to keep the air flowing into the engine cool!
