read, record, and analize data from 7.4L MPI
 

I will eventually be supercharging this engine and I would like to record performance parameters before and after the installation. What is out there to read and record ECU data? Anyone know of a good source for fuel pressure gages and manifold pressure gages?

There are a few diagnositc scanners available to read data and codes. I use the Quicksilver Digital Diagnostic Terminal. Others here on the board use a similar set-up from a company called Rinda.
