Ok I'm working with my tuner again trying to get my car back to where it was, things are better but definitely still having issues. I've got a new revision that helped out my fuel trims but still feeling an intermittent hesitation/miss. Not knocking his work at all, he's understandably busy so I'm just looking for a second set of eyes while I wait.

Where I feel the car having issues seems to be correlated to the map sensor bouncing around in the logs. Not sure if my sensor is going bad or if its just a symptom of some other issue. The sensor is a FBM 4 bar thats about 2 years old.


Here's a startup and idle log. There's one spot in there where the car had some issues

Here's the first WOT log I took. Things look alright with a small bobble on the map sensor around 4k

The second WOT log. Map sensor is jumping all over the place, could feel the boost changing as the car accelerated.

Thank you all for the help!
