Default Can EFI Live tune a 96 Vortec 350

I just got a Tahoe with a Vortec 350. Can we use the copy of EFI Live we have to tune it? I am curious what I can do that's better than a handheld

For 96-97 blackbox pcm you need good ole Tunercat or Jet spectrum.

Yes you can upgrade to the 01-02 model PCM Service Number 12200411
It is alittle involved though (wiring)
This is certainly a good upgrade for that year model

Default 411 upgrade on 97 5.7

I did this upgrade with help for some members of this forum and can't begin to tell you how much difference it made.
