What is the anticipated HP to the wheels with the mods you have? The extra boost may overshoot the capacity of the OE fuel system however that boost level needs to be reduced. You might first start by reducing the boost level to the point where the fuel catches up then take a look at things. Extra fuel won't cure detonation and a mixture of high boost plus lean fuel is lethal.

The fuelhead i have is the euro with lambda
the WUR is modified so no coldstart pressure
warm CP 3.1 bar
boost CP 2.5 bar
i adjusting the fuel map with lambda valve + Frankencis
and it runs now very good in all rpms i would say.
and one very good thing it is taking fuel like a normal car not stupid rich in some rpm/boost like before.
i dont know HP but it is a big change in the buttdyno 1.0 vs 1.3bar in the swing
i have lower the two maps to about 0.9 at higher rpm because there is not enough fuel for keep AFR there.
