I may be wrong but I thought the afr's would of been closer to 11 at top end?

Just looked at the graph and actually it doesn't look too bad but like Pete said above
The afr,s look a little on the lean side to me as though she's not getting enough fuel

What size injectors you got and are you running an aftermarket fpr?
I would also say torque is down as would normally be higher than that,
Have you got a l/w ally flywheel fitted?

I don't know about the afrs, I just left it to jez, it made 420 when it ran richer for some reason but it was too rich and he backed it off for now.

Genuine sard fpr and 700s I think so they're not on the limit there and don't know about the flywheel but will ask Carl.

Would torque be down coz of a boost leak?

no boost leak wouldn't really affect the torque as such as its relevant to the power she is running but I wouldn't worry about that too much as every car varies dependant upon what its running, ie crank lightened and knife edged will lower torque as well as a lightened flywheel so many factors could alter that

im no tuner or mapper but I do know that on boost she should really be in the 10s so I personally think shes running too lean

what fuel pressure is it running at base idle?

Don't know about the fuel pressure. Got Carl Sat next to me and he said it has got an os giken twin plate clutch with light weight flywheel and knife edged crank too.

As for the fueling I suppose everyone has a different opinion but he said 11.7 is bang on and 10s are very safe.
