Description
Power and Performance. Improve the power and performance of your 2018-2020 Ford F-150 5.0L V8 with a SCT SF4/X4 Power Flash Tuner that includes (1) Custom Lund Racing Tune File. There is a reason why Lund Racing has been setting the standard in Ford tuning for years on end. Forget the average canned tune. Your Ford F-150 deserves nothing short of highly customized, top-of-the-line, and vehicle-specific adjustments. Exclusively designed for a 2020, 2019 and 2018 Ford F-150 5.0L V8, this quality module unites everything you need to grasp the full potential of your first-class racer.
Safety and Performance Review. A Safety and Performance Review is automatically included in a mail-order tune or as part of our subscription Support Service (starting from the time you receive the tune). This eliminates uncertainty regarding your car's performance, as we can diagnose any potential issues caused by something mechanical or install-related.
To access Lund's Safety and Performance Review service, visit Lund's Support Site here, sign up, and submit a request containing your original order number. You will also have to provide the PCM Code, the Tuning Device Serial Number, and the full modification list. We will reply with precisely what we need data logged. * Currently, this service is only available on bolt-on mail-order tunes for 2011 and newer models.
Tuning Revision. Tuning Revisions for minor modifications are free of charge up to 6 months after you've received your initial tune(s). After that period runs out, you may opt for an additional support period. This service includes a data-log analysis per Lund's Safety and Performance Review Policy here, as well as minor tune revisions per Lund's Revision Policy here.
Remote Tuning Session. Remote Tuning Sessions are for required all power adder (including nitrous) and extreme naturally aspirated vehicles. These sessions include extensive data logging support for dialing in the modifications done to your vehicle. We will analyze the logs and send revisions until the tune is fully dialed in. Find out everything you need to know about Lund's Remote Tuning Sessions here.
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.

Review shared from Lund Racing X4/SF4 Power Flash Tuner with 1 Custom Tune (15-20 3.5L EcoBoost F-150, Excluding Raptor)
2019 Platinum - JeffTexas
Wakes up the Ecoboost!!
Tuner is easy to use, but the Lund tune wakes up the Ecoboost. It is almost too much power/torque. I feel like I'm breaking something when I floor it (Just joking). With the Lund tune my truck is an animal. Get it, you wont regret it.

2019 XL - fastlaneusa
What a difference!
The SCT X4 is nice and compact. The gauge options along with logging are easy to use. The Lund tune picks up a lot of power under the curve and drivability is improved. The process to have the tune setup by Lund was very easy, as was the install. Great customer service by Lund and American Trucks!

2016 XLT - ShawnB
John and his team are good.
Noticeable power gains about 4k rpm. Rev limiter is raised to 7k with firm 6k shift points. Power band through out makes stock look weak.

Easy to install. I mounted it on my steering column with some Velcro. Gives the truck a little extra pep and gets rid of that stupid speed limiter.
