1. STOCK

Just like it rolled off the show room floor. I’m guessing you won’t spend much time in this tune, but it is nice to compare sometimes and remind you how awesome you’re other tunes are.

2. HEAVY TOWING

Adds a sizeable amount power all through the powerband of the engine helping the truck hold speed while towing and reduces downshifts and gear hunting. If you don’t have custom gauges or a CTS, use this setting over light towing.

3. LIGHT TOWING

Adds a small amount power all through the powerband of the engine helping the truck hold speed while towing and reduces downshifts and gear hunting.

4. STREET

Clean, dependable power. Great for the grocery-getter, daily-driver diesel truck. No loping, smooth response and power when you want it. Designed to be completely streetable but don’t be fooled, this tune will put you in your seat and leave the competition wanting.

5. COMPETITION ONLY SLED PULLING/RACE – otherwise known as Beast Mode

Pushes the truck and its components to the max for the love of the sport, bragging rights, and maybe some money and a trophy.

All tunes come with the option of:
1. Being the envy of all your diesel gear head friends.
2. 2004.5 LLY and newer, turbo adjustments to decrease EGT cool down time at idle.
3. Tire size and gear ratio adjustments.
4. Smoothed pedal response.
5. Speed limiter removal.
7. Being switched with the EDGE Color Touch Screen (CTS) on LB7 and LLY trucks.
