Default DAM Drop! HELP

2017 sti purchased pre owned, stock.
I got an AP with a custom Etune,everything was great. Suddenly DAM dropped to 0.0..feedback knock was reaching -10 at times mostly around -2.0. Fine knock learn was all over the place consistent at -11.45, max boost of 8 psi. No audible knock either WOT numbers go away. Usually when I hop on the freeway DAM comes back to 1.0.

Here's one date log

Also I might add, my tuner strongly believes its false because of where the knock occurs, at low rpm low boost.

Logs with DAM at 0 already, don't really provide any useful info as it is reducing boost, reducing timing, and adding fuel already. Do a single pull (3rd or 4th) and post that log.

I zoomed into one area and dam was .5... However, your timing was in the negatives, like -5 - -6.

When I found one with DAM at 1, the timing was low, like 5 at 3k RPM. From what I am seeing, I'm far from impressed with the tune.

I'd like to see a single WOT log (without all the additional data to sift through) in 3rd or 4th gear from 2ish k RPM to REDLINE.

You think it can be a tune error? I will do that tomorrow when I get a chance!

I won't comment until I see the next log, but what I've seen so far, seems all over the place.

It wasn't like that when it was finalized.. I even tried the the stage 0 tune same result. Uninstalled completely and without the numbers you can fell the hesitation. At low rpm and the limp mode, or max boost of around 8psi

I'd start with a boost leak test. If that passes, do a compression test.
