Questions about the FICM programing

[jlo84truck]

whats so bad about the vxap1? I have the turbo sweep in my truck. at idle you can hear it sweeping the veins. the power running stock sucks. I was wondering if the FICM reprogram will bring my exhaust temps down a little. it seams like the temps jump up quicker than they should. does bill do pilot injection for the 6.0l? I'm hopeing for a mileage increase, right now I can get 20 mpg (lie o meter) on my truck running dual electric fans, instead of the clutch fan and when I hook a trailer up to it or a 18ft boat my mileage goes out the window. It seams like any kind of load on the truck the mileage drops to 10-15 mpg at 55 mph. does this sound like I need the programing or am I being to greedy for fuel economy? before I switch to electric fans I could baby the throttle and get 17-18 mpg at 55 mph and loaded with a trailer and three 18ft airboat hauls I would get 8-9 mpg. Will the programing clean up the exahust smell (no cat or EGR on the truck)? just smells like its not completely burning up the fuel. Thanks justin
