DoWerk Introduces Doug's 500whp B6 Avant Build

Introduction to Doug's B6 Avant

Added on 10.01.2009

Doug came to DW Garage looking for some more power in his B6 A4 Avant. He thought he did everything fairly well on its previous incarnation but still wanted more.

Both Doug and Jake worked together to formulate a plan that would really wake up his Avant. The next result? Fully built motor and custom hardware by Jake@DW Garage with custom Motronic tuning by Mark@AutoSpeed Performance.
