The only minor concern (too strong a word but couldn't find another) is the ecu I would say has pulled some timing just before 6000rpm to 6400rpm hence the slight dip in the power curve.
The AFR fuelling graph looks normal for ppp and sometimes find with the ppp sports cat it is running slightly different fuelling to that picked up on the dyno.

Thanks Simon, chances are that I will be in touch soon enough to book some time with you.
That said I am reluctant to go down the route of changing any internals, but I am aware of the piston situation that can arise with Subaru engines. Assuming it were to be mapped to the sort of power as you mention above, is that still within safe tolerances of the engine and components, or would it also require some physical changes as well to stop things going bang?
Thanks,
R
