I spoke to the tuner about my results, and after having it on the dyno he believe the valve steam seals might not be sealing properly. Reason behind this was smoke on back off, even tho all old oil should be out of the intake system (due to blown turbo). The car made 165rwkw at 12psi, with a boost controller that was not holding boost at the desired level, 14psi. (it top 16psi and bleed of to 12 psi). We will be investergating further.
