Do you have an added boost gage? How do you know you are not loosing boost?

Over about .9 bar above 6k rpm the stock system can start to run out of fuel.

A good dyno facility can monitor your Air Fuel ratio and the Boost level against TQ, HP.

Most are used to the A/F but you may have to shop around for one that dose the boost.
