Answer to "Anybody use an EGR Tuner?"I put on my egr tuner and pittsburgh power muffler on 2 days after my fleet air filter. I was in the 5.8-6mpg range before the upgrades. Now I'm in the 6.8-7.1 range. I am very pleased with the results. I'm expecting roi in my first month with these mods!

Answer to "average mileage increase for install"I just got my fleet air filter and installed it today. I haul trash, dedicated run, 2 trips a day for 410 miles a day. Most loads are between 70k and 80k. My set up is a freightliner Columbia day cab with a Detroit 12.7 L 455hp engine and 3:55 rears. I drive 55mph on the freeway, and 1/4 of my miles are in the city ( about 50 total stop lights in a day). My trailers are open topped and I'm empty half of the day. I had been averaging 6mpg 68 gallons per day. Today on fill up it only took 59 gallons 7.1 mpg! Needless to say i was estatic! I have no other mods on the truck I know it was only one day but I'll be more than happy to keep everyone in the loop!
