Description
25 to 30HP Gain*
Your Viper came from the factory with a lot more performance than your engine’s Powertrain Controller Module is programmed to allow. Why? Because of emissions standards, gas mileage, etc. You remove and send us your PCM insured, and we send it back ready for you to install! Average performance gains are 20 to 30 Horsepower, not including upgrade parts such as headers, exhausts, etc.
This PCM Upgrade is designed for stock Vipers or Vipers with some modifications (mild cam, cold air, headers). Upgrades include:
- Revised Premium fuel & timing tables
- Rev limit raised to 6400
- Skip shift off
- Cooling fans on 20 degrees cooler
Programming is performed by the nation’s leading experts in PCM Programming with over 20 years of experience.
* Many other engine programming services are available – just ask us.
