engine stubbles after acceleration.

[stemo76]

Just received my custom tune and for the most part its really nice compared to what I had before.

do have one problem that I didn't before. When I pull forward or even step on the brake and then give a little throttle and let off the engine pulses. not so much on the tach but more with diesel chatter. the more throttle I gave it more noticeable the aftermath. I assume this happens when I am decelerating as well but the movement of the vehicle covers it up(I have an auto). Does this on 80+ HP setting and stock setting.

Any suggestions? I have the autoenginuty tool so I can get some readouts but its pretty new to me so I don't really know what to pull up and look at and then to know what it should say.

thanks.
