The performance on my Stage 2 Golf 1.8t is a bit flat.:help:

It is an AUM, which is the same as the AUQ fitted to the LC, with K03s and DBW.

The spec is:
Stage 2 Revo map.
Forge FMIC.
Forge TIP.
Forge 007 DV.
4 Bar FPR.
Green replacement filter element in std air box.
Milltek downpipe/cat and exhaust system.

There are no apparent boost leaks - I've had some, but sorted them all out. I have pressurised the system with a tester so I am confident all is ok.

No fault codes are present.

Anyway here are the logs:

The maf reading is lower than I would have expected. Actual boost looks a little low, and why is the Run o2 adapt at 0% all the time?
 
going by the maf reading of max 158 then do the sum of

158x1.21 works out to 191bhp

looks like maf is starting to fail as boost looks fine

stage 2 should be flowing alot more than that around the 180 i think from prev threads
