Hi all,
Finally broke 500 whp on the Z4 stock fueling system with the following mods
Car:

Mods:
Kohlefaser Luft-Technik Induction System (by ECS Tuning)
ClutchMasters Twin Disk FX850 Clutch and SMFW
AR Design Catless Downpipes
ER FMIC
ER Chargepipe with ER Tial BOV
2.0" Silicone Inlets
Silicone Outlet
UUC Trans Mounts
Stock Fueling System
E70 Fuel
Max boost was 22 psi with 12*-14* degrees of advance timing on E70 fuel

The goal was to break 500 whp with as less boost as possible, and reasonable advance timing based on MBT. Some cars maximum brake torque (MBT) will be lower. No two cars are the same.
Another Z4 member with with DCT hit 479 whp just recently that will soon be in the 500 club also
Both cars are running stock fueling system with no issues
