I came across this web site for mustangs, WMS they are located in Canada. They have a tuning system that replaces the factory ECM and it cost $1149.00 plus shipping. Does anyone have experience using their tuning system? I'm thinking about getting this system so I can be the master of my own tuning. I know about PMS, Quaterhorse, Tweecer, AEM and others like Fast. Some of these system piggy backs with the OEM computer and other replace the computer, this system is the best price for those that replace the factory ECM.
