The intake valve guide seals are worn and are letting oil slip by under high engine vacuum--as when you let up on the gas. The only fix is to take the cylinder head off and replace the valve guide seals. This problem is pretty normal for an older car with high mileage. It will probably run just fine. Just keep checking the oil level and keep it topped up.

Sounds like you may have turbo failure. The bearings may be bad and running the engine would damage it more if a turbo fin breaks of and endes up in the pistons. If there is lot's of blue smoke from the tail pipe then it's your turbo, if not it could be your boost side pipe clamp or tube gone bad or your wastegate actuator. Good luck and hope this helps
piston rings are shot and your valves need to be replaced
have you been racing this vehicle or has previous owner
if you just bought the car im sure last driver had it semi decked out now you will need a laptop the cars software to reset vehicles computer back to factory settings
when owners drive there vehicles they set them up in a way so more gas and throttle can be applied you just need to reset everything back to factory settings on comp
and if that dont work you will definatly need to do an over haul
