Results with air filter removed as my enclosed filter is said to be restrictive, it does sound alot better and you can hear the DV recirc, but according to the logs airflow is less :S There is also absolutely no timing pull. I've noticed actual boost is sometimes lower than requested? This is stage 2 1.8t.

Didn't know until recently boost leaks can cause poor maf readings...

On my boost gauge where it used to quickly spike then drop instantly now it just goes to 19psi in a normal speed and drops slowly to 16...
