Stage 1 ECU Tune Performance Flash Gains:  

      • 122WHP @ 4000RPM 
      • 193WTQ @ 2700RPM

Performance tuning modifies torque limiter maps, boost levels, fuel maps, ignition timing advance 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.  AMG S and Performance models may have smaller gains due to high HP output from factory, but should results in the same HP/TQ output as base AMG models after being tuned. 

      • We do not offer cat delete software or tuning for emissions bypass.
      • We do not offer tuning services to the state of California. 

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

    BENCH TUNE FLASH:

    Remove the 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 ECU back. This is the safest way, as we can have a full backup of the entire ECU content.

    REMOTE TUNE FLASH: 

    No downtime!!! With this option, once an order is placed, we will ship you a cable, that cable connects to a laptop and we are able to remote into your computer to flash the car. The remote flash option includes the cost of the cable (which is yours to keep). If we are out of cables for remote flashing, we can offer a cable for rent with a deposit. (We will message you if this happens). In some cases, not all cars can be flashed this way. In that case, you will have to ship your ECU to us for a bench flash. *You will need a Windows 8 or newer laptop and WIFI to flash remotely (Apple, Chromebooks are not supported)*

    Please print out this form and mail it in with your ECU. ECU will not be flashed until the form is filled out and sent to us. Thank you.
