Hi everyone. I have a 2021 lc200 gxl. VDJ200 Been running perfectly fine up until a week ago. I have had the engine and transmission tuned and a torque lock up kit installed. It seems to be missing/coughing under load at 2000-2400 rpm. It sounds like the turbo is trying to spool up then stops and starts again. It looses power when this happens. Anyone had this issue? Can’t work out what it is and it’s very annoying. Cleaned MAF sensor and all wiring. Checked all hoses for leaks but can’t find anything. Any help would be appreciated
