I've tried everything
- Cleaned MAF sensor (checked by mechanic, working perfectly)
- multiple bottles of BG injector cleaner
- ERG cleaned
- Mechanic checked for leaks (none)
- Mechanic Checked the Cat - fine
- New fuel filter
- New 02 sensor
- Cleaned throttle body
- New spark plugs
- Changed fuel station
Nothing has helped.
LTFT is around -9.4
STFT is around the same ... both negative
Ideas?

How many miles on the clock? Have you did the valve adjustment? Also it is a good idea to clean the injectors using pressure cleaning.
