Correct. Do not believe it was ever software related but more of me over looking something more than likely. Will post factory and modified files in the morning once i am back to my computer. Thanks

Here is the stock file and the modified files

Let me know what/if you find anything
I have narrowed it down to the ECM not TCM tune.

I have found a crack where I stripped the threads on the PCV fitting that the fitting is basically just hanging leaving an exposed hole between the MAF and Throttle body. Could this be the culprit with the MAF getting a false reading at key-on?

At key on, that should not cause any problem... but during engine run that will cause problems.
Is the truck somehow just recognizing a flash?

Only other reasons I can think of that may be the problem.
1- Between the time I read the stock file and flashed the modified one I updated my V2?
2- I did not disconnect the negative on the battery when I removed the MAF and it is a reoccurring fault?
**I flashed the modified file right after using V8 but I thought like with v7.5 it cleared the DTCs whenever it rebooted the ECM?**
Using the scan tool couldn't find a DTC
Only other thing I know to do is put factory intake back on and factory files back in and drive it a few days, then re-read the factory files and create new modified files but will base the values off the files I had already built.

Maybe try working on a few changes at a time to identify which one is causing reduced power.
