that is the coolant temperature sensor, back of the head, two wire, blue connector. Check wire and measure sensor resistance with engine runing: it should be high resistance (2-3K cold) and lowe resistance (600-300 Ohm when hot).
Also check your air temperature sensor located on the AL pipe going to throttle.
Turbo: removing the W hose at the BPC and going for a drive should give you overboost - go easy on the gas pedal. If no boost than the problem is at the turbo unit (wastegate rod connector, ...).
Check also the Bypass valve by the turbo duct. Should hold vaccum if you suck on the small hose.
