Expertly calibrated and meticulously refined, DME Tuning’s ECU software for the BMW 535i is guaranteed to give you MORE of a good thing. More horsepower, more torque, and a more exhilarating driving experience by delivering usable power through improved throttle response and torque management. With additional ft. lbs. of torque through the mid-range, acceleration out of your favorite corner and onto the straight is noticeably quicker throughout the rev range. Important DME Tuning saves your stock/factory ECU settings so that you can revert your vehicle back to stock settings at any time. For OBD Tunes, we will ship you our DME Tuning Kit. If the ECU needs to be mailed to us, shipping costs for sending an ECU to and from DME Tuning is the responsibility of the purchaser. You will be charged return shipping at checkout. The ECU will be tuned the same day it is received and DME Tuning will then ship back the ECU using whatever method it was shipped in with. (For example: If you send in your ECU via Ground shipping, we will ship it back via Ground. If you ship it via Overnight, we will ship it back via Overnight.)
