TBI with TPI ecm???

[Kevin R]

Dual truck TBIs/4 injectors is an idea for a future motor.
Right now the thought is to run one instead of the 747 on my crossfire
project.
Main reason is to try and get a better/faster output with more parameters
when using a scanner.

At what point did GM go to something that can be configured thru connection
rather than burning and swapping chips, and can they be used in a 2 injector
setup like the xfire?
