    2017 WRX Issues after pro tune

    Please see attached datalog and advise. I was running my stage 2 WRX (turboback, intake) with an OTS tune with no issues. Same day I got protuned (with gs ebcs) my car felt slower, AF learning was way off (as far as -25), lots of hesitation below 3k rpms and DAM kept dropping as low as .3. After 4 revisions my tuner advised maybe my injectors were dirty, I had my 30k service done yesterday with no improvements. As soon as the car hits 0-5psi at max fine knock learn shoots up -8 and my car loses most of its power while hesitating despite it showing my psi is climbing. I have had several instances where feedback knock hits -9. I am unsure what to do at this point.

    Thanks in advance for any insight,

    With AF negative, it looks like the ECM is backing down the fuel.
