Using various tuning software, Gearhead Sales LLC has programs available that extract extra mileage and performance over the already pre-loaded programs provided by SCT, Edge, and Bully Dog . We recommend the default files in the tuning device for the average driver but if you want extra performance Gearhead can supply you with custom files after your purchase.
6 Liter Tune Descriptions for Stock Nozzle Injectors:
- Street Race Lite (SRL) – Awesome daily driver file (no towing) with butt kicking response, low smoke, and outrageous power. The best shifting all-around street file on the market period! Typical gains of 1-3 MPG have also been reported with this file.
- Studded SRL (SRL+) – The one up to SRL for studded trucks. Simply adds boost over SRL for 10-15 more HP and 50-60 more FT/LBS of torque.
- 8000 Lb Tow (8K Tow) – This tow file is rated for 8000 pounds of towing without being studded. Studded trucks can tow 13000 pounds with this file.
- Unlimited Tow – Since this file maintains stock fuel parameters, it can tow whatever you want while giving better shift firmness than stock.
- Extreme SRL – SRL+ have you craving more? This is the file for you!
- XX Tow - This tow file is set up for any after market injectors while trying to keep the EGT's (Exhaust Gas Temps) down.
- XX Reduced Fuel - With this file it add more boost and fuel for a more powerful street tune while maintaining drivability.
- XX Full Fuel - This file will be similar to the XX Reduced Fuel until you put your foot to the floor. Then you need to be ready for what we call "FULL FUEL". Go fast and eat cornbread!
