There are no PCM modules out there at the moment which will increase your hp. On newer cars the factory computers are calibrated fairly perfectly for the car. However if you modified your viper in any way the Roe piggy back box can increase your power output. Dont bother with the mopar ECU it does nothing but take away power according to most.
In about 3 months there is going to be a complete plug and play programable fuel/ignition/boost/nitrous/traction/etc.... box available for the vipers. It will be much more costly than the Roe computer, about 2k but is a totaly different beast.
