Programmers
Want power that you can use on demand? Then a programmer is what you need to unlock the full potential of your car or truck. Whether you are towing adding power or trying to increase gas mileage, programmers can dial up the right settings for you. Preston’s has found that so called performance chips only increase what the designer who created the chip wanted not what every driver may want. This can be distressing if you install it and it does not do what you expected, plus, you may not be able to return to stock. Programmers let you decide what’s right for you and if you do not like that setting then change it or go back to stock. Some of the features are:
- Shift Points & Shift Pressure
- Digital Displays For Exhaust Temp
- A Little Power Or Dumb Stupid Power
- Increased Torque
- Increased Mileage
- Tow Safe Mode
- Raising Speed Limiter
- Diagnose Check Engine Lights
These are available with many more settings.
