I've been trying to get that last bit of power out of my truck on a stock fuel system. my problem has been a commanded fuel drop past 2800 rpm. If i torque on it its fine as soon as i downshift it starts to tapper off downward to 122 cmdfuel at 3150 rpm. I've read every forum in this cummins 5.9L section and have tried a ton of different things ( one at a time of course). Here is a data Log. Frame 3600 shows it well. Any help would be awesome. Thanks
