I have a 2015 powerstroke 6.7 with a deleted stock power file it pulls great through all the gears if you manually shift it. but in automatic past first gear it wont build more then 10 pounds of boost or something like that

this is the ecm and trans file im using
At first glance, ECM file is a stock file with all the torque limiters stilled turned on. I compared it to another stock 2015 I found in the repository. Same with the TCM.
Probably something wrong with the magic in the background.. I would go back to your tuner to have them revise it to fix the issue
chances are, your tuner just has the codes disabled but you're still running in a "reduced engine power" in the background
