Until the truck has relearned it is not reasonable to either dyno or to use accelerometers, on the other hand 800 miles is enough to relearn.

Another subjective opinion from another Ross.
I perceive a noticeable gain in power, 1&2 gear do not suffer loss of power, but seem improved. Never had tire spin as I now experience on hard launch through 1st and 2nd, pulls hard on up the gears.
although I am not currently on my regular driving habits because I have the week off, my average mileage as shown on the display has increased from 15.1 to 17.2 mpg. Need more drive time to verify this increase.
I have an UC authorized tuning shop near me and they said that to tune would be $150. per hr with a minimum of 2 hrs required. they could not quote typical hp/tk gains,(have not done enough 5.7's, gains can vary) but said the maps provided from the UC factory were generally somewhat conservative, and there would be some gain to be had from additional tuning. Sadly, I cant do it at the moment.
