As you know, Dinan, the well known Bmw tuner doesn't like stock cars and due to this, revealed today a special performance software for Bmw 535i. As a habit, the tuner suits perfectly with the new car warranty coverage for up to 50,000 miles and includes the possibility of consequential damages. Same used on the Bmw 335i, the new Performance engine software rises the turbo-boost pressure from the standard 8.8 to 13.0psi together with properly retuned fuel mixtures, ignition timing and full map rescaling. More than 2000 engine functions have been recalibrated giving high increases in power output but also in safety. The engine is now capable of delivering 384hp and 421 lb-ft torque at 4300rpm.
