The SCT X4 handheld programmer is one of the most popular tuning devices in the EFI tuning industry. Simple to use and loaded with tons of other features it definitely makes the SCT X4 stand out amongst it's competitors. The X4 comes pre-loaded with several different calibrations for your vehicle which are proven to increase horsepower, torque as well as improve drivability and fuel economy. In addition to the pre-loaded SCT tunes the X4 is capable of storing up to ten custom tune files. So if you're looking for something more than one of the pre-loaded tunes any SCT tuner can provide you a tune for this device.
The device also allow for you to make user end changes to things such as spark, fuel, rev limiter, tire size, gear ratio as well as many other options giving you more control of your vehicle.
The X4 also has datalogging capability. What this means is that it will not only display in real time but also log and save information about the car while it's running to be reviewed at a later date by you or your tuner. Anything that's monitored by the PCM can be logged by the SCT device. Things such as air fuel, battery voltage, fuel pressure, fuel trims and MAF counts are all things that can be logged. Additional sensors can also be used to monitor other things that the PCM doesn't normally read on some vehicles (EGT's).
The SCT X4 can be easily updated through WIFI or by being plugged into your computers USB port with the USB cable provided with the device.
Lethal Performance is proud to announce that we now have custom tuning by Jon Lund of Lund Racing available for the 2013 GT500. It's not like the 2013 GT500 is a slouch from the factory but with one of Jon's custom tunes you can expect a solid 33-35rwhp increase as well as better throttle response and an increased rev limit on a standard 93 octane tune.
*Note: When purchasing a tune for an aftermarket blower/turbo application, a remote tuning session with Jon Lund is INCLUDED! This will ensure that the vehicle makes the most power possible, safely.
Ordering Procedure
Once you've placed your order for the custom tune a tune request form will be emailed to you. You'll fill out the custom tune request form with your vehicle information and once finished submit it. That info is what we'll use to make your custom tune with. Once the tune request form has been submitted a copy of it will go to our tuner Jon Lund. He'll create the tune file and either email it to you direct if all you purchased was the tune, or the tune will be emailed to us to be loaded onto the SCT device before it ships. If you're purchasing the remote tune/datalogging service instructions will be sent to you after the purchase has been made on how to schedule your remote tuning/datalogging session with Lund Racing
Lethal Performance not only carries the all of the top brands of performance parts for your Mustang but we also carry the best when it comes to tuning. That's why we teamed up with Jon Lund of Lund Racing to offer our customers custom tunes for their cars. Jon Lund of Lund Racing has been tuning cars for quite sometime. He's regarded in the tuning community as one of if not the best when it comes to GT500's, 2011-2012 5.0L's and 03-04 Cobras. His years of experience as well as countless hours on the dyno has given him the tools to offer mail order tunes with the performance of a custom dyno tune.
Not only has Jon tuned our 1040rwhp 9 second GT500 which was a 5.0 Mustang Magazine feature/cover car he also tuned our 2.9L Whipple powered 2011-2012 5.0L Mustang GT which runs low 10's and will soon break into the 9's.
How the custom tuning works is we collect the information we need from you about your car. A tune request is made to Jon and the tune is built to the specific mods you have on your car. Then the tune is then emailed back to us. We'll email you a copy of the tune so that you can upload it onto your SCT handheld device as well as keep a copy of it on file so that if you happen to lose it for any reason we can resend it to you. The tune we provide will still allow you to make changes to it through the handheld device. Things such as spark, gear ratio, tire size, rev limiter are all features of the tune that are left open for you to make changes to if you choose. All of the tuning that we provide through Jon Lund is only good for SCT's products.
Updates- For minor changes such as adding a different intake, pulley or headers there is no charge. If you happen to upgrade from a stock blower to a Whipple or Turbo setup there will be additional charges as those setups are unique and require additional tuning. The same goes for a race gas or valet tune as those are additional.
If there are any options that we don't list when you're placing your order please write them to us in the comment section during checkout. Someone will contact you once the order has been placed to make sure we have everything we need from you to have the tune made.
