Hi,

it's my car, i done mechanical tune, but soft was not my job (but i'm not 100% happy with this).

Full equiped from factory except M-pak but i try to install all parts.

Mechanicly big FMIC + 2.5" open DP no kat

On stock map with this changes 230hp/450Nm

After mapping:

First result
263hp/560Nm

After N75 change

268hp/580Nm

But i have EU3 injectors "131", this spring i plan to use "219" from 535d and bigger hybrid turbo.

Why is your torque is dropping so fast?

Original, small sized turbine creates plenty of back pressure to the exhaust manifold when the amount of burning fuel is increased from ECU. That's my opinion. Turbine wheel dia. Is only ~45mm. Engine needs the hybrid turbo :angel: Better-flowing exhaust and stiffer exhaust valve springs also help with high rpm power. Of course there can be some limits on ECU but I am not able to tell anything from those because the lack of excperience :mrgreen:
