Check the turbocharger and its related components, such as the boost pressure sensor and vacuum lines. A malfunctioning turbo or a leak in the vacuum lines can cause power loss at higher RPMs. Ensure there are no blockages or leaks in the intercooler and piping as well. Let me know if this helps or if you have any further questions!

Inspect the EGR valve for any blockages or malfunctions, as it can cause power loss if it's stuck open or not functioning properly. If the EGR valve is dirty or clogged, cleaning it might resolve the issue. Let me know how it goes or if you have more questions!

Inspect the catalytic converter for any blockages or restrictions, as it can cause power loss if it's clogged. A clogged catalytic converter can restrict exhaust flow, affecting engine performance. Let me know if this helps or if you have any further questions!
