The BMW N57 3.0L inline-six diesel engine is known for its incredible torque delivery, efficiency, and long-term durability. With TuneZilla’s expertly developed calibrations, this powerhouse gains even more low-end torque and midrange response—transforming everyday drivability while retaining factory-level reliability and smoothness.
Our calibrators optimized boost control, fuel delivery, and torque management to extract the engine’s full potential. Whether towing, daily driving, or highway cruising, the N57 becomes noticeably more responsive and powerful across the entire RPM range.
Description:Stage 1 is designed for vehicles running factory hardware. The calibration refines throttle response and torque management to achieve smoother acceleration and more usable power in every gear—all while maintaining OEM drivability and emissions systems.

Custom Tuning starts at $1999. To get a more accurate cost on your custom tune, please create a ticket and tell us more about your build, and your specific modifications.
If you feel that our existing tune offerings will not work for your application or your intended use, you can request Custom Tuning. Custom Tuning must be requested through our Tickets, and you must provide vehicle information as well as hardware (upgrades) information. Once submitted, our team of calibrators will evaluate your request and determine if Custom Tuning can achieve your goals and if they are able, your Tune Request will be accepted.
Custom Tuning requires heavy participation from the Customer, either through an Authorized TZ Dealer or the Customer themselves. TuneZilla Calibrators will require that the vehicle has access to dyno time when needed, and data logging is required. If you are not comfortable with data logging, and if you may not be able to access a facility with a dyno (many facilities will rent dyno time) custom tuning may not be possible for you.
Custom Tuning vs. Off The Shelf Tuning
We understand that our end users have varying driving styles and build purposes, which is why we offer revisions on all of our Off-The-Shelf tunes. By offering Custom Tuning to our customers, we can be sure you are getting the most out of your vehicle with your specific parts upgrades. Our OTS (off-the-shelf) maps are tested in house with as many variables as possible to ensure even if you don’t want to customize your tune, your vehicle’s OEM sensors and adaptations will still be able to optimize our tunes to your region’s fuel and most bolt-on upgrades. Tune Revisions are not the same as Custom Tunes. See our Terms and Conditions for our re-tune policy (section 4b)
We believe it’s important for our customers to understand what is happening inside their engine so they can make informative decisions. Our LOG VIEWER automatically generates your vehicles data log .csv files into easy to read graphs which can then be viewed by our Calibrators to find areas of optimization on your vehicle. Not only can this data be used to optimize your tunes, but a lot of troubleshooting and diagnosing can be done by comparing requested data to actual data at a glance.
In many cases, custom tuning is not required. If you are unsure if you will benefit from a Custom Tune, you can reach out to our team and upload data logs for them to examine.
