Everyone who has gone from Phase 1 to Phase 2 has confirmed that P2 offers more power. I wonder what changes Roush made to achieve that.
The VMP and PBD tunes seem to have increased the performance of the P1 kits. I would be surprised if the tuners could pick up much if any over P2 and still keep it reasonably safe on 93. As far as I know, no one with a P2 Roush calibration has gotten a custom tune.
