          stock ecu the car made 330bhp.dropped the boost a touch and tweeked the map now making a nice 320 at around 12/13psi

          no reliability issues at all and its all on a stock motor.
          ...superior horsepower through knowledge,good design and maximum efficiency
          version 1.0 a low boost 347bhp
