good point Xen
if a mapper could divulge information that would be great
I guess the mappers haven't been following this thread.
I am not a mapper but I do have extensive knowledge of this.
Boost wont affect fuelling as the fuel pressure will rise exactly as if the car
is driving correctly irrespective if the throttle is open or not as air is
metered using a map sensor that measures off the inlet manifold as is the
pressure control bleed for the fuel regulator.
Extra fuel is needed and mapped in addition to provide thermal managment
for the heat load and strain put on the turbo.
I.E. Extra unburnt fuel cools the exhaust gas.
