Code it to the alpina display and remove the alpina logo. Increases to 200.
Increased boost is the easiest way to make power on these cars. Increase boost paired with air/fuel/timing/ignition so the car runs efficient.
Alpina changed the components to ensure proper cooling and turbo efficiencies but mostly to maintain long term reliability. Increased boost creates heat and heat in turn without proper cooling will increase IATs and pull timing. You lose power. I imagine if we were to do a couple head to head pulls between a tuned 750 and an alpina you'll find the alpina will run cooler and maintain more power.
