I'm assuming you meant IAT, not AIT! There must be two sensor locations for measuring intake air temps. I'm assuming the default IAT PID chosen is located in the intake air manifold. I'm not sure about the other one.
MAF, of mass air flow, measures the amount of air being sucked through the intake. I'm not sure why there are 3.
I run IAT, ignition Cyl 1, boost (pre-throttle), coolant temp, EGT, knock detected, oil pressure

So what is the actual boost? And when you upgrade turbo and "increase" your boost (say to 20/21psi) do you increase the pre-throttle or DME target?
How do you know if the boost is working well?

A quick way to add a real-time boost or other gauges is to purchase and plug in one of these Bluetooth connectors into your OBD2 port near the driver's left knee. Please see attached photos. It has phone apps to add gauges and performance testing like 0-60mph and 1/4 mile. Inexpensive and works well!
