1. Any fault codes ?
2. Check FICM voltage first...should be between 47-49v
3. If above is all good, sounds like the turbo variable gate vanes are likely sticking to me...turbo needs removal and disassembly to clean the variable gate vanes and housing and unison ring, may also need turbo repacement if things are worn inside.
