Which the final mapping done do you think 300 is attainable wiithout nos?

 

I should be well past it.  Also thinking about increasing the rev limit by 500 revs to make use of that extended upper power band,

Over 400 lb/ft aswell. How hard is it to get all the power down??

Its fine, because the peak torque is at 3500 - 3800 revs, not under 2000 revs like you get on a smaller turbo.   So I get no spike of power at all.  However, I do get turbo lag due to its size, so I just need to be aware I cannot really floor it properly until probably about 2300 revs which is when full boost builds and kicks in.  It's very much a top-end power car which is why I need to raise the limiter by 500 revs so I can bloody use it....
