Bill:

You did ask about installation. You disconnect the vacuum hose to the wastegate and plug it. A new hose gets fitted from the wastegate to the device and to a "T" fitting included in the installation kit that gets fitted between the vacuum hose coming off the drivers side of the intake manifold and the manifold. You get the pickup for the boost gauge there as well. That's about it. Leave the adjustment at the factory setting until you get a sense of what the car is doing. They claim that is a safe setting and I concur. A boost gauge is an important tool to get a measured result. Then go one turn at a time to determine differences. I recommend you stay very conservative until or unless you have a air/mixture gauge to be certain you are not creating too lean a burn. The oxygen sensors have the ability to correct minor changes but there are real limitations. Hence reprogramming becomes the absolute solution. But drivability improvements are real and the installation can be reversed in minutes.

Good luck.
