when i mention horsepower im vaguely referring to trucks overall power, but say peak torque at 2050 minus 15% torque, your at 300ft lbs of torque under advertised power at 1200rpm.Maybe my initial question was confusing, the tune change didnt effect the gauge readings, a power loss happened before a tune change, i only mentioned i changed files to give some background history on the truck. I feel like alot of people see a problem like this and just deal with it and call it a dummy gauge, however its hard for me to understand why one day it would quit going to 100% is all. Just trying to learn maybe how that gauge is calculated and if i do have a power loss i would like to resolve it
