Modified M106 Motor Data :
Modification to the 745 Motronic computer program allows unlimited increase in power and torque.
The practical increase is dependent on several other setups in the car and engine.
Typical increase is 100-150 hp together with some modification of wastegate or to wastegate's control system.
Power levels of 350 - 500+ HP and torque over 640 Nm are possible.
There are many ways to increase boost. You can either have a fixed boost level or a adjustable boost control.
One of the best boost control systems for 745's was the Tuoma Perfection adjustable wastegate,
but that is not available at the moment and may not be manufactured at all anymore.
The standard 745i 3.4 L engine gives 252 HP at 0.3/0.5 bar boost. Engine cutoff is set to 0,7 bar,
which many of the 745 owners have unfortunately experienced.
This modification to the computer program removes the cutoff limit and sets all necessary parameters for unlimited power.
The program is dynamic, so performance is optimal at any and no boost conditions. Torque is increased also considerably.
As a rule of thumb this program increases power by approx. 50 HP for each 0.2 bar step:
0.7 bar = 300 HP, 0.9 bar = 350 HP, 1.1 bar = 400 HP, 1.3 bar = 450 HP, etc...
The standard 745 turbo is good at least upto 1.5 bar.
