Another Issue: On turbo models, there is a vacuum controlled switch, located near the pump (red cap) that cuts the signal to the APC solenoid valve when the cruise control is on (switch opens). If the switch is faulty (I broke mine on rough road), it can keep turbo boost at the "basic" level even if the cruise is turned off. The APC boost gauge will only go half-way into the yellow region, and performance will suffer. Either replace the vacuum controlled switch or pull the pigtail connector below the switch and short the ends of the yellow/white wire going to the APC solenoid valve and
proper turbo boost should return. Be aware that if this second fix is employed, your turbo is not limited in boost when in cruise control.
