WHEN YOU ORDER A KIT, TUNING DEVICES ARE SHIPPED SEPARATELY!
The TuneZilla is a handheld programmer that connects to your vehicles OBDII port and allows you to tune your ECM without removing it from the vehicle. The TuneZilla allows you to upgrade, downgrade or reset your ECM to stock as you wish. Though this tuning method adds a bit of cost, it saves you the hassle and down time associated with removing and shipping out your ECM.
Here's how it works: First we ship you the TuneZilla programmer, you plug it into your cars OBDII port, download your stock ECU ID file, we will then send you the new tuned file for you to upload to your car.
** The TuneZilla program is Windows only however, there is a tutorial on how to run it on a Mac here **
If you're thinking of upgrading your 335d or X5 with a DPF & EGR delete exhaust kit? Then this tune is what you'll need to get it done! The Stage 2 tune offered by TuneZilla will unlock the brutal potential of the M57 engine without compromising any of the engines internals.
