what is better on a 1.8T for power / performance, overall best? I am very new to cars and things all together, and im looking for a point in the right direction.

lean with a BOV because not all of the air is being sent back through the MAF and confusing the ECM in the process. There are hybrid BOV's that don't throw fault codes(most of the time). But IMO it's not worthwhile mod. just pick up a DV.
