Check engine and 32mpg normally 40

[theaterlightman]

My tdi is experiencing low fuel economy, 32 mpg in the past ive gotten 40mpg with a 2 bar map and vnt17 turbo.
Ive gotten a check engine light with intermittent excess fuel in the exhost and when i looked at my egr it was gunked up so i cleaned it. I was wondering if my problem a dirty intake or bad fuel injectors. Listed below will be my readings.
Mas air flow 300 mg/str
Boost pressure 1020 actual and specified. It runs about 7-10 psi at 75mph and had the tune done by a shop near by. New vaccume lines and verified boost pressure and response/ sensor.

Injection
Cyl 1 -.75
Cyl 2 -1.25
Cyl 3 2.87
Cyl 4 -.85

Fuel consumption 1.8 l/h
All above is at idle

O2 sensor 3.69 at idle and 16 when cruising at 45 mpg

Also cam was already replaced, turbo, vnt17 was added at 160k miles, currently 223k 5 speed mt with new synchros. Ran on b100 70k- 160k miles of its life. New axles at 163k miles and tune done at 180k miles. I drive low rpms but dont lug, and have a spirited drive on payday (every other week)
