The boost I needed

Great product, easy to setup and straightforward. It does have an OBD-II port, and is a little thick but software updates and simple and tech support is helpful. The difference between level 2 to level 4 is obvious and having a k&n 77 series as well as Magnaflow exhaust helps, I notice the low level RPMs are much smoother, especially when that extra passing power is needed.
