It is not hard to test an intercooler. Pressure drop and temps and in and out are what mostly tells us how good an intercooler is functioning.

There is something called a differential pressure gauge. It shows the difference between two connections. Or just use two MAP sensors.

I would think we would want to measure at the turbo discharge and just before the throttle body. After the throttle body would be good to but then any pressure loss from the TB would be included. This would include the intercooler plumbing and tanks in the measurements.

Temps are usually measured at the in and out of the intercooler.

Same with turbos and exhausts. Good tuners measure the pressure reached in the area before the turbine and sometimes before and after a turbine to see if what they have built is working as it should. Mufflers can be tested to pressure loss to.

Ambient compared to turbo output temp lets us know if the turbo is operating in an efficient range.
