is this normal?

[neil_jdmr]

I apologies in advance for being pushy but as above.
 
Do all fd\'s drop off after 7k

On the first turbo and up to 6.5k on the second it holds a steady 0.85bar
but after 7k it has dropped to 0.6 then even to 0.5 by 8krpm.

Is this normal behavior.??

The car is bone standard by the way with an exception to hks racing suction kit.
 
I have corrected/changed everything that was not already brand new ( hoses/pipes/turbos/sol\'s/valves etc etc)
 
I am gonna fit a blitz nur spec next as iam now thinking its maybe being restricted on the exhaust side.
 
Any help greatly appreciated
