Fair enough, that'll make it easier to test the sensors then as I was thinking I needed to test the sensor on the manifold itself. Ultimately I'm just trying to sort out why I get overboost at anything over 21psi on map 6, yet I've read of @ 535_BiTurbo pushing upwards of 24psi without issue. I'm not sure if a 2012 550i is TU or not, but there's gotta be something that can be done to push past 21psi -
