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!
6 Liter Tune Descriptions for Larger than Stock Nozzle Injectors:
- XX Tow - This tow file is set up for any after market injectors while trying to keep the EGT's (Exhaust Gas Temps) down.
