Hi, I took my Toyota Yaris 2007 D4-D 1364cc to Toyota authorized service unit, they told me that: No fault codes found. But that the turbo is overboosting (doble 1.6 bar). And because the fuel sypply is not beeing compensated the car is lousing it's power over 3000 revs.
Were can I send my engine computer to be tested? And is it the computer the problem or it can be the turbo control as well.
Thanks

Boost is controlled by an electronic wastegate. Have Toyota test wastgate operation. Running it lean and overboosting will burn a piston and blow a turbo seal or snap a shaft.
