Probably your boost solenoid valve.

I had the same with mine, it was sticking open so turbo wasn't running 100% efficent. Used to get to 70mph and cause issues. Replaced it and good as new and so much faster.
Link below to what solved mine.

I also found the vacuum hoses had holes in mine , ended up having the replace all of them , but always good to know about the turbo actuator sticking open

Sounds like the classic low pressure fuel pump to me. It's probably worth checking the pressure with a live data diagnostic equipment.

You really need to look at the ECU live data. The low fuel pressure should be around 360Kpa but definitely no less than 320Kpa.
