Tuning Details Explained:

 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 8,000 pounds of towing without being studded. Studded trucks can tow 13,000 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!
