Description
Tuning for Gen 5 (Direct Injection) 5.3L with SCT Devices
Unlock the performance your vehicle was built for. Preloaded SCT tunes deliver real-world horsepower gains, improved drivability, and have user adjustable options like DOD/AFM disable.
If the preloaded tunes don’t meet your needs, we can deliver a custom tune, or you can add-on custom tuning when you place the order.
Note:
SCT only supports the 2016-2019 GMTK2 Yukon with the 5.3 on the BDX device. The 6.2 requires custom tuning with HP Tuners. Please do not order this if you have a 2016 Yukon with 6.2 engine. The 2015 Yukon is different and the 5.3 and 6.2 are both supported by the SCT X4 and BDX. The 2015 Yukon is a different product listing on the website.
Typical Gains
- Up to +20 HP on stock 5.3L
- Improved throttle response, shift quality, towing performance, and fuel efficiency
- NOTE: SCT does not support transmission tuning for 2016+ GM vehicles.
Supported Modifications
- ✔ AFM/DOD Delete
- ✔ Long Tube Headers, Injectors, Intake Manifolds
- ✔ Cold Air Intake, Catback Exhaust, Shorty Headers
