So I am trying to dial in my tune and have been having issues getting my speed density dialed in. It seems to want to always calculate the MAP higher then it actually is in some areas no matter what I do. I have checked my fuel pressure, injector data, and have dialed in my MAF curve multiple times. My injectors were cleaned and flow tested what they should have. Recently I noticed that the air load seems to exceed what i think is possible for this motor. Im thinking something is causing this is also the reason for the SD tuning issues. I keep coming back to thinking its the injectors/MAV curve but my fuel trims are +/- 2% and the curve looks perfect.
The build
2015 GT
ported Gen 3 intake
mildly ported heads
sleeved and rotating assembly 10.2:1 compression
Stock cams
stock throttle body
Custom built twin turbo
Below is a screen shot of a log where at a MAP of 54 (11.5 lbs of boost) its reading an air load of 2.0

Attached is the current tune. Runs and drives well its just that Calc MAP and Air load that doesn't seem to line up.

Im really running out of ideas here and anyone with some direction or insight would be greatly appreciated.
