Been confirmed by the branch manager that it is indeed BHP at the crank, and when I put my glasses on and looked a bit closer at the charts it does say eng power and eng torgue, but having looked at the eurocharged dyno charts on here it seems to be pretty much on a par with those at around 170 RWHP/200 Crank HP
I've now cleaned the injectors and egr valve (pretty clean anyway) and swapped the oem air filters with BMC carbon dynamics, so it breathes a bit better. That's definitely made a difference low and mid range. Much more responsive now. Seat of the pants dyno tells me so, but also when my wife drove it, without knowing anything had been done, she came back and demanded to know "What have you done to "my car?" and why is it louder?"
So overall quite happy.
Now just need to make up some pipes and hoses for a full dual CAI instead of the air still going through the now empty original air boxes.

Thanks for all the help and advice guys.
