I have a 2003 subaru impreza wrx only has induction kit everything else is standard/stock it was recently rebuilt with closed deck shortblock, been having problems main one being the car will not idle with maf in... just idle hunts so low it stalls, but will run and idle fine with maf out, i tried a diff maf (wasnt new) and it did the exact same thing? Replaced intake manifold gaskets and checked for leaks did compression test, checked coils/plug gaps etc, there is also no error codes wen its idling low/stalling.
The other weird problem is my head unit is toast as its getting power and solid ground, But.... the rear of my car chassis is not grounded so my amps couldnt possibly work now as there grounded in boot!? but the front of chassis is showing ground lol the ground thing sounds impossible to me lol makes me think somethings bad with wiring/ground and its all related
Any help would be great!

Sometimes those "power adders" are problem makers.

Do you have a scanner that will show iac counter?
I might try cleaning the throttle body and then resetting the PCM, then idling and driving it to relearn.
Thinking you might just be at maximum idle air correction and there's just no room for the iac to increase air flow.

During that capture you were 50°c min, max & avg. So it never changed during the capture which doesn't necessarily indicate a problem depending on how long it was running and how long you were logging.
(50°C × 9/5) + 32 = 122°F. Thanks Google
If you can make a custom data list I would include:
Engine RPM, Desired RPM, IAC position, ECT, IAT, whatever throttle position data you have and engine run time (if available) and watch it warm up a little from a cold start without giving it any throttle.
