Get More Power Without Losing Everyday Driveability

Looking to wake your truck up without making it hard to live with? The Street Tune is exactly what daily drivers have been waiting for. It gives your 2014 LML Duramax a noticeable bump in power and torque without compromising reliability or comfort. With gains of up to +110 RWHP and +198 ft-lbs of torque, this tune delivers quick throttle response and smooth acceleration that makes your truck feel lighter and more responsive in all driving situations. Whether you're commuting, cruising, or just enjoying the drive, the improved power curve makes every mile more enjoyable. You still get to keep your factory emissions equipment intact and stay 50-state legal, which means no headaches with inspections or compliance. This is the tune for someone who wants a fun truck to drive without getting too wild. It’s designed for the everyday diesel owner who occasionally tows, hits the highway often, and wants a clean, crisp upgrade to their driving experience.

Calibrated Performance With Emissions Safe Engineering

Behind the wheel, this custom Street Tune brings together over 100 precision calibration changes that optimize your factory ECM settings. Built specifically for the 2014 6.6L Duramax LML, the tune was developed to provide maximum usable power without compromising the engine, transmission, or emissions system. It retains your truck’s factory turbo braking feature and avoids altering any hardwired systems or sensors, keeping your install clean and warranty-safe when used with the SPADE EFI Live AutoCal V3. The result is better throttle sensitivity, reduced turbo lag, and a more efficient use of fuel and air, helping your truck perform with less smoke than generic box tuners. This tune is ideal for trucks without major performance mods, but it works well with transmission tuning if you want even smoother shift points and better power delivery. Designed to keep EGTs in check during everyday use, it still delivers a surprising punch when you need it. If you’re looking for a safe, street-legal way to enhance performance, this tune strikes a solid balance between power and peace of mind.
