... It works, becouse the stock injectors are not able deliver enough fuel by 3.5 Bar. Running Engine after 5500 RPM, the mixture getting lean, opened the fuel injectors @ 95% PWR by custom tune, but with full time opened, not enough fuel available for Lambda 0,87 ~ 0,88.

With the 4,0 Bar Pressure Regulator, the fuel pressure is higher, and the injectors are delivering more fuel into the cylinder. With the custom tune and a 90% PWR, Lambda 0,83 is able - we only needed 0,87.

Under partitial load, the mapping is running a little bit rich, but lamdba-adaptions are ~ -1,38 on 1-3 and -0,83 on 4-6. Perfect.

Getting ~ 320 HP and a failure-entry in the gearbox "over 400NM"
