      Power and Performance. Improve the power and performance of your 2018-2020 GT Mustang with a Lund Racing nGauge Tuner that includes (1) Custom Tune File. When your Mustang rolled off the assembly line, Ford programmed it to cater to the needs of the daily driver, not the performance enthusiast who adds aftermarket bolt-on modifications in the search for more power. So, if your Mustang is bone stock or if you have added a cold air intake, throttle body, exhaust or other bolt-on performance upgrades or even running a Boss 302, Cobra Jet or GT350 intake manifold, you'll need a Lund Racing custom tune to see the full power potential that these aftermarket mods can make.

      One Custom Lund Racing Tune File. When you order a Lund Racing nGauge Tuner, you aren't just getting a tuner. You're getting the tuner and 1 dyno-tested custom tune file that is written specifically for your Mustang and your particular modifications by a Lund Racing calibrator. By optimizing the air/fuel ratio, adjusting ignition timing and tweaking cam timing, a Lund Racing Custom Tune will squeeze out the extra power Ford left on the table. This tune requires the use of 91-93 octane fuel or E85.

      Free Tune Revisions. Lund Racing will provide tuning revisions for minor modifications free of charge for up to 3 months after you’ve received your initial tune. Changes to your air intake, throttle body, exhaust, gears are all considered minor modifications. The countdown starts from the time you receive the tune(s) which may be up to 7-10 business days following your order.

      Virtual Gauges and Warning Lights. Using the live data from the OBD-II Diagnostic port, the nGauge Tuner can be used as a Virtual Gauge to monitor from 1-6 different parameters at once in real time. Users can even customize colors and set warning lights, such as RPM's for perfect shifts every time.

      Data Logging and Monitoring. The nGauge Tuner makes it easy to read and record multiple data channels simultaneously for in-depth evaluation of engine performance. The nGauge can store data from your vehicle's PCM/ECM directly to a MicroSD Card, allowing you to view popular sensor data such as EGT, Air/Fuel Ratio or any other 0-5 Volt source. Data logs export as CS files that can be viewed in Excel or any data logging software, including HP Tuners Scanviewer. Additionally the nGauge features 2 analog inputs, ideal for monitoring boost and AFR.

      Daisy Chain up to 7 nGauges. The nGauge Tuner was designed to allow you to connect up to 7 nGauges together in a daisy chain configuration. This is ideal for those looking to keep a close eye on all of their Mustang's critical systems.

      Diagnostics Tool. The nGauge Tuner can also be used as a diagnostic code reader. Save yourself hundreds of dollars each year by reading and clearing your own Diagnostic Trouble Codes (DTCs) rather than paying a dealer to do the same. It's as easy as a few simple steps.

      Additional Features. The nGauge Tuner has a full color, 2.40-inch, 320 x 240 LCD resistive touch screen display with a touch stylus included. With a thin space saving design, the nGauge can be installed in different size gauge mounts with the included standard 2-1/16 adapter ring. The nGauge also features convenient power saving modes including Auto Sleep/Wake with ignition and Auto Dimmer.

      Quick Flash Times. Unlike other Handheld Tuners on the market for the S550 Mustang that can take up to 20 minutes to load, the nGauge Tuner will install its first flash tune in under 5 minutes, with subsequent flash updates installing under 1 minute.

      Easy to Load; Easy to Restore. When you load a tune on your Mustang, the nGauge Tuner automatically stores your vehicle's factory settings. To return the vehicle to its factory settings, simply select the option to restore the factory settings, and you're done. The nGauge Tuner can hold hundreds of different tunes via a MicroSD Card.

      Will Not Ship To California. Due to state regulations, this product cannot be shipped to addresses in the state of California. Lund Racing will not write or provide custom tune files for residents of California.

      Application. This Lund Racing nGauge that includes 1 Custom Tune File is specifically designed for 2018-2020 GT and Bullitt Mustang models equipped with the naturally aspirated 5.0L V8 engine. Aftermarket camshafts, aftermarket and/or ported Heads are not supported with this tune.

      Application Notes. For Mustangs running pump gas with basic bolt-on modifications, see part# 405892. For Mustangs running E85 with basic bolt-on modifications, see part# 405893. For Mustangs running pump gas and an aftermarket intake manifold, see part# 405894. For Mustangs running E85 and an aftermarket intake manifold, see part# 405895.

      **Please Note: The nGauge ships blank from AmericanMuscle, the custom tune files will be emailed directly to the end user within 4 business days from Lund Racing.

        Truly Makes a Difference

        I read a majority of reviews on everything and I have to say this is a must. No matter if it is just for minor bolt-ons to force induction, the nGauge opens the car up and unlocks its potential. I can't recommend this enough.

        of course its good!

        but after having it mounted for over a month now, i dont really see a reason to mount it permanently. its just sits there and i dont have no practical use for it daily or even weekly. if u get it just use it to load your tunes and store it somewhere.

        It’s so much better

        The ngauge is a nice device but dealing with Brandon at Lund was awesome. The car is awake and so much more alive! It feels like a muscle car and not a bloated cruiser!

        Lund pump gas tune

        I am very pleased with the Lund pump gas tune. My car runs much better and it definitely shifts better. I drove 150 miles and got 33 miles per gallon

        American Muscle and Lund made this a easy purchase. I know this is a small mod but it is my first of many and the response time is noticeable with the extra power. Was my first time installing any thing to a vehicle and with AM and Lund they made this a confident buy and easy install thanks again

      any idea what the cost is to also include an e85 tune with the 93? thanks

      • The tune would only be written for either e85 or 93 octane fuel and would not be cross-compatible.

      How many custom tunes can it hold?

      • The nGauge can hold 10+ tunes on the supplied 4GB Micro-SD card, depending on the size of the tune files.
