Push Your Duramax To Its Legal Limit

If you’re the kind of driver who wants to feel every ounce of power your 2013 Silverado or Sierra HD can legally produce, this Sport Tune with EFI Live SPADE is built for you. It delivers up to 135 additional horsepower and 243 ft-lbs of torque, turning your truck into a completely different animal the second you press the pedal. The throttle response is razor sharp with zero dead pedal, and the acceleration feels lighter, faster, and more aggressive without compromising emissions compliance. Whether you're looking to light up the tires at the track or just enjoy a more exciting commute, this tune brings the kind of performance that makes driving your Duramax something to look forward to every day. And because it’s 50-state legal with emissions equipment intact, you can run it confidently without worrying about inspections or restrictions. It’s the biggest rush we can legally pack into a single tune, and it’s perfect for truck owners who plan to build more power in the future. If you’re done settling for stock performance and ready to feel what your LML is really capable of, this is your next move.

Precision Tuned For Power Without Compromising Compliance

This Sport Tune is a fully customized calibration designed to maximize performance while maintaining full emissions compliance for your 2013 6.6L Duramax LML. With over 100 changes from the stock file, it refines every aspect of engine behavior, from torque delivery to throttle mapping and fuel pressure, giving you a sharper, more responsive driving experience without cutting corners. Paired with EFI Live’s SPADE AutoCal v3 hardware, the tune is easy to flash and update, with no need to hack into sensors or wiring. This particular tune is 50-state legal under CARB Executive Order D-845, which means it’s cleared for use in even the strictest emissions regions. While the power gains are impressive, the tune is also engineered to retain factory systems like the turbo brake and work in harmony with ZF6 manual transmission trucks. For best results, especially under heavy load or competition conditions, additional upgrades like a low-pressure lift pump, upgraded CP4, and transmission tuning are recommended. It’s a smart choice for serious enthusiasts who want high-output performance without compromising drivability or reliability.
