        Does actual screen need to be connected at all times or will you be able to disconnect and still keep the tune active?

        • No, you do not have to keep this tuner hooked up to your Mustang for the tune. As soon as you install the tune, you would be able to disconnect the tuner and the tune will still be active on the car.

        So if i buy this tuner and then decide to buy other performance upgrades such as air intakes, exhaust, headers, camshafts ect. will the tuner be able to recognize any brand of aftermarket parts. will i need to tell the tuner which parts i get by brand or size or what?

        • The SCT GTX Tuner will not recognize any parts itself, and will need parts to b e specified. Some parts will require custom tunes and will be incompatible with the default strategy tunes.

        Helpful (2)

        So just buying this can add power? Does it just ask you questions like what is done to your car?

        • The SCT GTX Tuner will come preloaded with SCT's default strategy tunes. Once a tune is loaded to your car, you will typically see gains of 15-20hp. We recommend going with a tuner that comes with custom tunes from a tuning company such as Bama, VMP, Unleashed or any other reputable tuning company, as these will typically offer more power with tunes specific to your Mustang's build.

        I've been using nothing but chevron 94 my 2016 gt mustang. Does this tuner have that in its program? Cuz I'm not down grading. I'm very interested in this tuner.

        • The SCT GTX Tuner will have pre-made strategy tunes, which will have octane settings for all commonly used fuel octanes in the US. The closest to your 94 octane would be 93 octane, and the tune will work, as you can always use an octane rating higher than what the tune is rated for, but not lower.

        Will work on a 2013 f150 stx with the 5.0 engine ?

        • This device would be specific to the 15-17 Ford Mustang GT. It will be loaded with pre-configured tunes for the specific application.

            SCT GTX

            Sold my LiveWire TS , and used the proceeds to buy this one. Definitely worth it in my opinion. Love the display, functions, and that you can disconnect the tuner so easily. Touch screen is super responsive, and looks great.

            Looks good

            Looks good, does what its supposed to but the canned tunes are very limited. Only 1 tune for headers, and no tune for the candl cai but a few others. I should have got the livewire so i could get free tunes because now i have to pay for 2 seperate tunes

            Just getting started

            I purchased this tuner with a tune required CAI. You can select from dozens of CAIs already loaded on the device. You can also select your fuel/octane and idle RPM. It looks nice, and you don't have to leave it in your car, but I like the extra gauges. I'm just getting started on mods. I have cat-back, and I want long tube headers and a whipple stage 1. I've done tons of research. This tuner will work perfectly.

            Great buy!!

            Does all it says. Also comes with a simple tune for mild builds. Best thing it does a crank relearn. Easy directions quick setup and I did it all on my phone hotspot.

            Great device for your car

            Easy to install. Comes with everything you need. Flat cord to be easier for Concealment. Fast and simple software setup with the operation of the device. Engine runs smoother and adds more mid range torque. After updating device through wifi, be sure to make adjustments needed with the customized tune option under the download tune icon on the main menu. Recommend a test ride as soon as everything is installed.
