We have 2 methods of having this tune installed (Flash Type Selection).
Method 1 - BENCH (Recommended): Remove the DDE/ECU and mail it in. We will create a full back up image of your ECU without opening the lid or any physical damage to the ECU at all. We then upload our tune of your choice and mail the DDE/ECU back. This is the safest way, as we can have a full back up of the entire ecu content.
Method 2 - REMOTE FLASH: We have an available option of flashing your ECU/DDE remotely through the OBD2 port of you vehicle without removal of the ECU/DDE. This requires a $400 refundable deposit. Only downside is even though it's completely safe, we cannot make a back up of original data, only write new tune. There is also usually a wait between 0-15 days for remote kits to become available, as we have to wait for other customers to return them. Remote flash kit time is limited to 1 week per customer, after that the deposit will be deducted at $25 per day that it's late.
Any of our Stage 1/Stage 2 tunes, help with throttle response, more power/torque, and improve MPG of your vehicle. It's literally one of the best mods that you can do to your diesel BMW.
Here's a few dyno graphs of our tuning to show the improvements between stock to stage 1 to stage 2.
