BMW N57 Performance Tune for USA N57 2014-2015 F02 740LD.

F02 740D N57 Stage 1 Performance Flash Tune Gains: +65WHP peak +85WTQ peak

 Crank HP/TQ Numbers based on our dyno results:

    • Stock   ECU:  255hp 450tq
    • Stage 1 tune: 330hp 550tq

Performance tuning modifies torque limiter maps, boost levels, fuel maps, and more. All to help safely increase HP/TQ, while keeping good drive-ability and factory fail-safes/limp protection in place. Factory emissions remain functional and are not disabled. Gains can vary on vehicle condition and location.

    • We do not offer EGR - DPF - DEF disable/delete/bypass tuning.
    • We do not offer tuning services to the state of California.

We have 2 methods of having this F02 N57 ECU tune installed (Flash Type Selection).

F02 740D N57 BENCH TUNE: 

Remove the DDE/ECU and mail it in. We will create a full backup image of your ECU without opening the lid or any physical damage to the ECU at all. We then upload our tune and mail the DDE/ECU back. This is the safest way, as we can have a full backup of the entire ECU content.


No downtime!!! With this option, once an order is placed, we will ship you an ENET cable, that cable connects to your vehicle's OBD2 port and Ethernet port on the laptop. The remote flash option includes the cost of the cable (which is yours to keep). 
-We will send you a link to download our OBD2 flasher software in an email after your order is placed. Once you have the cable and flasher software, you can then follow instructions to request your tuning file via email. After you receive your tuning file, you can then flash it your self anytime you'd like, if you have technical difficulties and cant figure it out, we can connect remotely via TeamViewer and assist. Be sure to type in your VIN at checkout.
-*You will need a Windows 8 or newer laptop  (Apple, Chromebooks are not supported)* 

Please print out the tuning form below and mail it in with your DDE. If you're doing a remote flash you can email it.
