Description
Up to 25–35 HP Gain*
Your Viper (1996–2002) was programmed at the factory to limit performance due to emissions standards, fuel economy, and other factors.
You remove and send us your PCM, postage insured, and we return it ready to install. Typical performance gains range from 20 to 35 horsepower, not including additional upgrades like headers or exhaust systems.
This PCM upgrade is designed for stock Vipers or Vipers with mild modifications (mild cam, cold air intake, headers). Upgrades include:
- Revised premium fuel and timing tables
- Rev limit raised to 6,400 RPM
- Skip shift disabled
- Cooling fans activated 20 degrees cooler
Programming is performed by the nation’s leading PCM experts with over 20 years of experience. * Many other engine programming services are available—just ask us.
