Really could do with it on VCDS to rule out boost gauge...

You are running on actuator pressure only, the N75 isn't allowing any more boost. Lots of reasons for this, but a fault code read is your first move.

So I feel a little sill I had a another look over the engine today
And found the MAF sensor was unplugged abit.
Now it's boosting around 5 and 6 psi

Thats good its running higher but shouldn't it be 11/12 psi? I don't know if the autos are differnet but shouldn't most 1.8t's run higher than that...
Stage 0.25 S3, as Audi intended it, except with a little wear and tear. And a few extras
I'm a little unsure?? I was told standard psi is around 8?? I could be wrong though?

Grrrrrrrrrrrr. If you *****es don't know, don't postyou'll only confuse the poor man.
Shauns car has an AGU engine, so has no boost sensor so it can't be checked on VAGcom or a solus. the ONLY way to measure boost on the AGU is via a mechanical guage.
Also, 6psi is about bang on for a standard 150bhp AGU. 10psi is for an AJQ/AUQ 180bhp engine.
Sounds like it's running fine to me Shaun, MAF logs looked good when I came out with you, peaking around 120g/s which is bang on for a standard car.
