6.0 Bucking
So i have been working on this problem for a few weeks now and cant seem to find the right answer. I have a 2006PSD 6.0
At about 60-70mph my truck will start to buck/jutter if i give about 5-10 percent throttle. It only happens at these speeds and i tried all sorts of fixes so far. Also there are no codes. Truck starts and idles great. At more than 10 percent throttle at 60mph, it acts normal. My current fix is just drive normally at 80mph
I also see talks about the possibility of the Turbo vanes being stuck, but wouldnt that happen at other speeds also?
Oil Change,
Fuel filter change
EOT and ECT within 8 degrees
FICM Change with Atlas 40
EGR Replacement (Unplugging and driving didnt change it.)
Replaced IPR valve
Turbo cleaned at 90k (Currently 140k)
Visual check of exhaust system and up pipes and no leak
Current mods
Fabtech 6" Lift
FICM Repair.com with Atlas 40
Blue Spring
Coolant Filter
Edge CTS
4wd ESOF hose kit
SS Brake Lines

Any idea what your ICP and IPR duty cycle readings are? When it is lugging and bucking and carrying on just generally, have you tried manually downshifting the truck (don't do this at too high a speed, mind you...) while maintaining speed to increase engine RPM to see if the issue goes away?
