If you use that basic setup it will give you a decent tune. The reason is that the turbo map sensor uses a different scale then the NA one so at the same manifold pressure it is sending a lower voltage to the ECU. The 315cc injectors compensate for this by adding more fuel at the same duty cycle. The BTM must be added because when you trick the ECU like this it adds timing.
Whatever you do... do not use the stock injectors. At stock fuel pressure they will run out at around 150rwhp which is less then you will make at stock boost pressure.
