ISX 870 vibration - oldgms - 10-07-2018

So I have been chasing a pretty bad vibration with my service truck for two week's, I changed every mount looked this thing top to bottom and couldn't figure it out, only did it under a load weather hard or easy load, so i decided to start looking at the calibration( I bought this truck this way) And that's when i found it, The truck was factory 8520 CPL which is what i inframed it to, after looking someone had put a 565@1850 Torque 8518 CPL in this thing,No wonder it was so violent during acceleration. So i used Calterm and put in the proper CPL 450@ 1650 Torque and guess what? The vibration is gone and this thing is so much smoother. Goes to show, Look closely at what your Buying( lesson learned)
