Ah! No, those temps are both measured with a thermocouple and the ecu doesn't have the ability to register those. Unless you have an expensive adapter box...
Today was a dyno day, but on the way there, I had almost no boost anymore. Engine runs very well, but no boost
I checked and even removed parts of the intake and downpipe (turbo spins fine, no play), but couldn't find a leak or anything, so I returned home. Still no clue as what the cause is.
