One is when i am at zero throttle going down hill or flat road the car starts to hunt or lunge around. AFR bounces between 12-18 either let off the throttle completely or add more throttle and it clears. No codes and the map sensor was cleaned after this was started.
Two is Car is only hitting 13.4PSI. set is 18.5 for the past two years via bren road tune. Boost leak test came back fine no leaks. Also changed the waste gate control solenoid (EBCS) no effect.
Car is 05 outback 92k miles no check engine lights. engine temp is steady 185 regular stage 2 setup with oem intake. Turbo is the original VF40.
The 13.4 psi i have no idea past the turbo's waste gate is failed.
The pulsing afr with almost no throttle register 1% is their anything in the throttle body that may cause this?
I have Data logs from the event as well
Could use some idea's thoughts one what may cause the issues so i can get my car back running 100%.
