Whether you're hauling a trailer, merging onto the highway, or just want the fun of a faster throttle, there's a tune here that fits. It keeps your emissions equipment intact, so you're legal and compliant in 49 states without sacrificing power. You’ll feel a noticeable difference in throttle response, torque delivery, and overall drivability. It's the kind of tuning that makes your truck feel new again, without overwhelming you with unnecessary complexity. From landscapers to weekend warriors, this pack gives you the performance boost and flexibility you need to enjoy your truck every day.

Clean Power Gains Built For Real World Use

The FIVE Tune Pack from DuramaxTuner.com delivers a full range of custom tuning with over 100+ calibration changes from stock, engineered specifically for the 2014 6.6L LML Duramax platform. Each tune is designed with safe power delivery, factory turbo brake retention, and intelligent air-fuel ratio limits that help reduce soot. The Sport Tune gives you up to 135 RWHP and 243 ft-lbs of torque, while the Heavy Tow and Light Tow options balance torque increases with Smart EGT control to manage temps under load. The Street and Optimized Stock tunes offer smoother throttle and better drivability when you're not pushing the limits. Each file is emissions-intact and designed for trucks that still have their factory emissions systems. Combined with the SPADE EFI Live Autocal V3 device, this setup gives you reliable power and total control over how your truck performs in any scenario. It’s built for trucks with or without mods and integrates seamlessly with TCM tuning for the best shift quality and transmission behavior.
