Hi all, so recently had a turbo change and by looks of it a new actuator. Problem I'm having is sometimes when driving the car will have very little power until over 2k revs then boosts fine, the engine noise changes too like a tappet or loud diesel sound, when it goes away is boosts normally which is available from 1.5k and car goes super quick. Happens alot when I pull away. Any advice on what this could be?
