In most cases, more than 90% you don't need to adjust anything, we will send your system fully adjusted with best overall settings to your particular make and model. If for any reason you need to adjust the engine interrupt time also known as the "engine kill time", the RPM threshold (this is where the quickshifer becomes active), shift sensor motion PUSH PULL or the MAGNUM levels we've made that more than simple without the need of expensive equipment, complex programs, dyno runs or anything else but wish to do so!
