Get More Out Of Every Drive Without Compromise

If you’ve been craving more response and muscle from your 2013 LML Duramax but still want to stay emissions legal, the Street Tune from DuramaxTuner.com is exactly what your truck needs. It adds up to 110 RWHP and 198 ft-lbs of torque, completely waking the truck up without taking away from everyday drivability. You’ll notice smoother throttle response, faster acceleration, and a power curve that actually makes the truck feel lighter. This tune is made for people who drive their trucks every day but want that extra edge when needed. It doesn’t require any major modifications or complicated wiring, just real gains, made simple. And with the EFI Live SPADE hardware, flashing the tune is quick and easy. Whether you're driving to work or towing on the weekend, this tune keeps your truck fun without getting in the way of reliability. It’s the perfect middle ground between stock and all-out race mode.

Smart Calibration That Respects Power And Reliability

The DuramaxTuner Street Tune is built with more than 100 calibration changes to your factory ECM, designed to enhance performance while keeping your emissions system intact. The tune provides the most horsepower and torque possible within OEM-safe parameters, offering a strong balance of fun and function. The smoother power delivery reduces strain on driveline components, while maintaining the factory turbo-braking feature for safety during deceleration and light towing. SPADE tuning with EFILive AutoCal v3 allows you to flash, update, and even scan engine diagnostics, all from a compact handheld device. With support for multiple VINs and unlimited tune updates, it's a future-proof setup for any Duramax owner. For trucks with larger tires, turbo upgrades, or built transmissions, adding TCM tuning is highly recommended to get the most out of this calibration. It allows the engine and transmission to work together more efficiently, improving shift timing, clutch engagement, and drivability across the board.
