Puts the ball in your court.

Matt has heaps of options to optimise the drivability.
Are you pre or postFL??? Auto or manual?
Anyway you really want to log the avcs vvt angles asap.
Cheapest way is to find a local member with the tools and knowledge, or a mechanic/auto shop with an SSM scanner, or grab an android phone with otg, an otg adapter to suit, a blue vagcom plug from an au vendor on ebay, and the Btssm android app.
In addition to logging and LV you can display virtual gauges on the android device, great if you want eg boost, corrected speed, digital coolant temp etc...
