Hellloooo!

Why don't you scale your map better. If that is really load in % down the side rather than kpa is there no way you can increase the resolution? You running alpha n, speed density or some sort of blend?

I can see if i can dig out some of the maps i did for Cols ZT way back. GT30 turbo but similar CR so off boost stuff should be ok to use as a starter.

I seem to remember having figures for WOT on boost of 13/14 degrees around max tourque rising to 18/19 degrees as the revs increased and the cylinder filling dropped off. This bit will be different for your engine / turbo combo.

I also agree, get some super in there you tight arse!
