That is where the Ultracharger from APR for the 3.0 TFSI V6 comes into play:
What APR is doing is removing the throttle body as a restriction which should improve flow and reduce pressure:
That 93 octane 421 AWHP figure is 28 awhp higher than without the Ultracharger. On race gas, the Ultracharger provides another 13 awhp.
For maximum efficiency, you will want the dual pulley setup plus the Ultracharger. Definitely worth the $1599.99 if you want to maximize your 3.0 TFSI output.
