yes.... spartan kit... 40 hp - 350 hp... recently installed.
came with turbo back exhaust and AFE air intake.
Was running stock no DPF, then tried 150 hp, didn't like it at all. Loaded 275 and ran it one night before i noticed this issue.
I tell you, i don't race or bag drive, but the 275 tune was just what i wanted. I was able to cruise down the highway with 4lbs of boost. Mileage up for sure.
what is the cause of this? we have this car also and have been very happy with it,less than 30k .You have this trouble also? I drive it on short trips when I don't want to start the 6.4 and like how the trans moves to a high gear quickly for good mpg's ,seemed to downshift well for freeway passing too .is this discussed in another forum somewhere?

Not real sure, but my guess is the torque converter. My car has been flawless, but I only have 17,000 miles on it so far! I just posted to illustrate that under different conditions the engine can move quite a bit. I suspect bad motor mounts had something to do with this though...
