The Cam Tuner is a plug-and-play solution that compensates for the installation of an aggressive cam. It will work on the Dodge Hemi, SRT-10 and Viper applications. It is designed to be an easy-to-use solution that end users can install and adjust themselves.
A more aggressive cam profile is a tried and true way to improve performance. In a speed density engine management application, a more aggressive cam results in less vacuum at idle and light load. This lower vacuum causes the Powertrain Control Module (PCM) to run too rich. The Cam Tuner corrects the fuel curve for the correct fuel mixture at light load.
