I sell Holley, but on stock '09-up Gen3's I recommend the MS Gold. It IS plug and play, controls VVT, MDS, and the active intake. It also doesn't require a separate coil driver like the Holley or a VVT lock out. Again, let me state I'm a Holley dealer and love the stuff, but I can't sell $2500 worth of control that doesn't control the VVT, MDS, or AI (won't even get into the lack of trans control for NAG1). I can sell a $1400 MS Gold system that will, and then a $700 NAG1 controller, and have a customer with a '09-up Gen3 that can truly just swap a modern powertrain.
