The popular Shrader Cammed Idle tune is also available for your 2011-2017 Mustang GT with any tuning purchase! This special tune gives the car a unique lopey cam sound when idling, which gives it that signature sound that people have come to expect from a performance Mustang. Using the variable cam technology of the 5.0 Coyote engine, we are able to move the camshafts in a more favorable position for cam lope. This change to the programming of the PCM will not affect normal driving performance, and is not active during WOT (wide open throttle) performance. It is only active in off-throttle engine idle situations. Check out the video of our Roush RS2 with this same tune to hear it for yourself.
As part of your tuning purchase from Shrader, we will include two (2) tune files designed for use with premium gasoline only. The first tune will be our performance tune designed for 93 octane for normal cam operation, and the other will be with the Cammed Idle feature (if you have chosen to add that feature during checkout). We have done extensive research on our Dynojet to come up with the most power and torque, without compromising or risking the health of the engine.
You can switch between the tunes at any time by reflashing the car with your programmer. An SCT handheld programmer is required to use our tunes. If you already have an SCT programmer, we will send the files to you by e-mail and you can download it into the device yourself. The instructions for doing this are located here on SCT’s website.
We can also make adjustments for other basic bolt-on upgrades such as a cold air intake, GT350 intake manifold, Holley Sniper intake, and aftermarket headers. So please select the proper dropdowns below. We do not provide remote tunes for supercharged or turbo cars, but we can do a custom dyno tune on our Dynojet if needed. Call to schedule that appointment.
All tuning is developed in-house by Shrader Performance using SCT software. There are no returns allowed on custom tuning due to the nature of digital files, but if you have any issues, we will work with you quickly to solve any problems with your order.
This order page is only for the 2011-2017 Mustang GT and Roush stage 2 with Coyote engines.
