Good info @
moto-mike, exactly what I was after. Making the power is one thing but having to work around limitations isn't worth it. I'll stick to pump (98 RON here, 93 in the US?) for now.
Assuming there was no further hardware progression, what size injectors and pump would you recommend to support optimum tuning on the SPS/69mm pulley kit?
