One reason why I like the conservative mapping by Revo. That and because the installer who is my service agent is on my doorstep.
My turbo has a 60% duty cycle for 330bhp. Quite safe.
That refers to the N75 duty cycle, right? Mine is doing a bit less than that, for what I recall seeing with PolarFIS. At what rpm are you referring that 60% duty cycle, so I can check next time on mine? 
I have to be honest and admit that I can't really answer your question
, it's what Jim told me (JKM) when he mapped it and set it up.
