Actual not keeping with requested boost

[GaryM]

wouldn't it just be better to lower the boost at high revs so the turbo can actually get somewhere near the requested, can't see the point in having the requested so high knowing it'll never match it. At least if they were closer it'd be easier to spot potential problems later on i.e. boost leaks and such

Its something I'll be having a word with James about as Im at JBS this coming weekend for a tweak.

The turbo will still be going flat out even if the requested was only 50mbar higher than actual. The main reason I run mine at B4 is to curb the low end torque for better driveability - it makes the same peak power on B4 as it does on B9, just the peak torque (boost) is lower.
