***PLEASE INCLUDE YOUR TRUCK YEAR, CABLE S/N AND ECU S/N IN THE ORDER NOTES OR YOU WILL NOT RECEIVE YOUR TUNES!!! ***
 
***PLEASE STATE WHICH TUNE YOU WOULD LIKE, VIA EMAIL OR ORDER NOTES, ALSO STATE TIRE SIZE***
 
Multiple tunes to choose from:
High Pressure (by request, usually for trucks with larger turbos and fuel), Medium Pressure (perfect for tuned trucks or even stock if a firmer shift is desired), Stock Pressure.
High shift points (for trucks with 37in tires or larger), Medium shift points(stock to 35in tires).
No skip (shifting gears 1-10) or Skip shifting (1-3-5...).Our no-skip files will always skip shift at WOT for better efficiency. 
 
Benefits:
- Increased holding capacity to accommodate higher power levels and increase longevity.
- Shifting schedule reworked for a smoother, more responsive driving experience.
- Tow Haul/Exhaust Brake downshifting schedule changed for better braking. Makes a drastic difference slowing down a load behind the truck. Truly a brake saver!
- Quicker TQ lockup and shifting. 
- 2nd gear start in sand mode for race use! 4x4 Launch friendly :) 
- Torque management retained during shifting for longevity. This is crucial.
