I have a 2010 6.4l bone stock minus a small off and bigger tires. 133k original miles. I’ve serviced it, filters recently replaced and fluids changed. But here recently I feel like the turbo is lagging maybe? And today I tried to gun it and the truck jumped and felt like it was going to stall so...
Buddy of mine had some issues earlier today. His truck idled fine nbut when put into drive it would lunge forward and felt like a standard when you let the clutch out with no gas.
Its straight piped with spartan tunes and a cold air intake
