calibrations

o.k, i pulled these calibration #'s off my hyperpac. VXC4NK.HEX,AMZ2AL.HEX,FDCANABS2. Dont know what all this means but i do know that after my truck got updated at dealer in june of 06 my milage went from 18mpg at 80 mph down to 14mpg! Not only that but it never started as well on cold winter days as it did the previous 2 winters.

Are you sure its not VXCF4NK.hex? If it is then you have a good program, thats not to say Bill won't roll you back to the factory one, if you want him to.

Yes it is VXC4NK.HEX, there are 3 numbers there i pulled from computer. Spoke to Codey today and had a few questions answered, but it sounds like Bill is the 6.0l go to guy. I'm not sure why my mpg and cold starts were affected so negatively after updates but something definately changed!
