Hi guys, i'm totally new to car tuning and turbo boost hardware and configs but i just took over a golf gti 2.0 which has been pretty well tuned up.
Problem is after 2 months of driving, i realised a drop in the car's hp and the turbo gauge doesn't go beyond 0.5. Usually it hits over 1.0 easily with very slight pressure on the pedal but now even at almost full pedal it stays at 0.5 range.
Can anyone help advice me what is wrong before i bring it to for a check?
If it helps there is a APEXI auto timer and a boost enhancer small device installed in the car though not exactly sure what it does.
