Feels like there is no power sometimes???

Hey guys, I have noticed that with this dual turbo set up there still is a great deal of lag especially climbing a grade and not getting into the pedal heavy. Does anyone else notice that you have to give the go pedal a good push to build a high amount of boost for grades? I was wondering if this is normal or if I should have my truck looked at. If I am starting from a stop and give it a quarter throttle it really bogs, I have to give it more throttle to go, then it builds a high amount of boost 30 plus pounds and takes off. Is this how everyones are, or do I have a problem? Just wondering thanks. By the way the dpf is not clogged as far as I know, and I have been going through regens once a tank or so.

Mine is different than I am used to as well. It does seem that you have to give it a good deal of the go pedal to get any significant acceleration, especially compared to the 05 Dodge that I sold. Building boost is not a problem, though -- I routinely see 20psi of boost with little to no acceleration. It really seems that this setup does not get near as much bang for its boost as either the earlier or the comp's current offerings.

This is correct. It takes a lot of pedal to do anything. And the truck makes boost wayyyy too easily. On the highway going up a .0000001% grade, they seem to want to make 20lbs of boost. This is one reason they get such terrible fuel mileage. they LOVE the boost.

And The 6.4l has more lag than my 04.5 Dodge Cummins with a Single turbo did.
