This page is where I'm gathering information and details about the GM TPI swap I'm working on for one of my 1973 Buick Electra.
I prefer TPI for the potential added control, though I fully admit than in my circumstances that may be more of a "looks cooler to me" type of decision and your thoughts may vary.
But, since this is my page and my cars, my opinion counts for a lot no matter how biased it may be.
This page is focused on the "hardware" for this swap - the computer, sensors, actuators, solenoids, pumps, relays, and the wiring harness to tie it all together.
It is not meant to address how to tune the resulting TPI system after you create it.
If you do not want to go that route, various sources for custom "EFI swap" harnesses are available, go Google for them.
I prefer to wire things myself and want to be able to take a pile of wire stubs and connectors and turn them into a wiring harness for just the cost of the wire and some new terminals to go into the connectors.
TPI also requires more fuel pressure, so it needs a different fuel pump, but the fuel system requirements/designs are pretty similar.
TPI does allow for finer fuel control in more advanced systems, though TBI does a pretty darned good job on a stock or reasonably-close-to-stock engine.
The BCB-60 holds a wide range of gear including Boss compact and Twin pedals and select stompbox models from other manufacturers.
