A recent mechanical service has indicated the car is generally in good health, but they raised some potentially major issues
- The pillar boost gauge is not accurate. It's not reading as high as it should.... but it still reaches nearly 30 PSI boost
- The aftermarket turbo is probably not tuned right to be outputting that much boost for the car

There is so much intake noise, that when the car is on the highway, you have to shout to other passengers in the car.

I am trying to find a dyno place that will help re-tune the car to a safe level before something bad happens.

I will see what happens when I get some work done on it.
