Doe's anyone know of a company that offers custom chip tuning for forced induction Audi's? I have a 1999.5 A4 1.8TQ with ATP's GT28RS tubro kit that I would like tuned.

Are there any good generic tuningoptions for thisGT28RS kit? I currentyl have the Mika tune fueling kit that's absolutley horrible.

Vast has a great line and they custom do everything and not to much money also
