whats up guys,
I have been trying to find this low power issue for about a year where ive exhausted myself of ideas.
It makes boost, perfect vacuum no leaks etc. but the car feels like its heat soaked 24/7. laggy and no torque at all. im thinking its something not playing nice with the tune anymore , maybe the ecu asking for less.
I have VCDS and there's no codes. Ive tried to log a few basic things but nothing stood out and im not sure what to look at next. So any guidance would be massively appreciated
No codes so completely stabbing in the dark
Cheers

No codes so completely stabbing in the dark
- Changed spark plugs no change
- Maf is reading low, but tried a working one with no difference
- Changed VVt unit last year to a decent but non OEM, no codes or issues after but tried a working OEM VVT solenoid and no difference
- Checked the TIP and turbo for mechanical issues, none except a small crack on the wastegate
- aligned the throttle body
- pressure tested
- cleaned sensors and TB
- car never overheats but it easily gets heatsoaked and stuck at 5psi from mild traffic
Cheers
