Does not properly fire injectors
I purchased this for Flowing and cleaning injectors, and the power supply is too weak to accurately fire injectors, any kind of instructions is a joke, not enough actual control of injector pulse/time definitely would buy a cheaper model then just add the gdi box pretty disappointed with this for 3 times the price as old model and same weak/control issues as previous models
