Of course I smoothed out each time. Come to think of it, this is also an 07 manual. Do you think that by chance it may be an OS issue?
    You said you tried raising pulse, that'll make it worse.
    It needs to be reduced until.it's happy, it's a commanded fuel problem...too much too quick

    If you don't mind sending me the tune, I can do some adjustments to try..

    Bringing this back up, I have an 06 that does the exact same thing. Did you ever figure out the problem? Thanks

    I haven't seen the truck I was having issues with for awhile so no progress here, however I must eat some crow on my modded FCA comment above! I have installed an arson III kit from Shane at Motorsport Diesel in a new pump and installed it on my truck and WOW! It performs above expectation and flawlessly! Ok sorry for the derail.
