Make sure you pick up some of that goo remover that is recommended. I applied that to one side, let is sit for a minute, and scraped it off with the backside of a plastic knife. I did each side 2 or 3 times. This ensures a good connection.
To read boost you will have to tap into the green map wire behind the glovebox. There is a good pic of it on the vortex buicks site.
Julio "Razor" at alkycontrol makes a really nice plug and play kit to log fuel pressure. It plugs between the tps connectors and the transducer screws onto the fuel rail. Only have to run the one orange wire into the powerlogger auxillary block.
Not sure what version of PLC is sent out currently but it may be outdated. It is best to download the most current version off the fullthrottletech forum. This will give you the correct .ini file that you can enter your fuel pressure transducer data into.
Really a good investment and installation is pretty easy. I hesitated to buy one for a few years because I was intimidated by the install and the use of the software. Glad I finally broke down and bought one.
