ECU Tuning for 2014-2018 535d/X5d by Tunezilla for N57 3.0L Diesel 2014-2018
With up to 80hp and 132 ft-lbs available with a stage 2 tune, you owe it to yourself to see how BMW really wanted your 535 or X5d to feel. It goes well beyond just a jump in power, throttle response and smootheness have been improved, combined with the right exhaust fuel mileage can increase as long as you can keep your right foot in check! For those wishing to have a mild upgrade from factory the Stage 1 offers a modest 60hp gain with all the same benefits.
