I don't think it should have boost at idle... :dunno:
CHECK TURBOCHARGING PRESSURE
(a) Install SST (turbocharger pressure gauge) to the pressure
regulator with a three way.
SST 09992-00241
(b) (MIT models)
Accelerate the vehicle with the throttle valve fully
open after driving at 3-speed at 1,000 rpm.
Measure the turbocharging pressure when the engine
speed is over 2,500 rpm.
Standard pressure: 0.39 - 0.53 kg/cm2
(5.5 - 7.5 psi, 38 - 52 kPa)
-I
(c) (AIT models)
From a stationary state accelerate the vehicle in "L"
range with the throttle valve fully open. Measure the
turbochargining pressure when the engine speed is
over 3,500 rpm.
Standard pressure: 0.34 - 0.42 kg/cm2
(4.8 - 6.0 psi, 33 - 41 kPa)
