CAM LOBE SEP & EFI??

[Vettepilot]

Well, ok. Let's say that at least for one of my vehicles, I stay with it's original OBD1 TBI system, but want to tune it for a better cam, heads, and exhaust. It's a 1994 GMC K1500 5.7 4x4. I already rebuilt the throttle body, and did all the mods to the throttle body itself to improve it for performance. Use will be mild everyday with about 10% offroad. What, exactly do I need to tune it and where do I start?

Second vehicle. 1987 Corvette. I am installing a hot 454 big block, and would like TBI. Big cam, many other engine mods. How to TBI/EFI that one??

Note: I do have an ALDL cable, a laptop, a tablet, and TunerPro and "ALDLDroid".

Also, yesterday I scored a "7427" ECM along with it's wiring connectors. Useful? Also, out of the Vette, I will have it's original ECM multiport 'puter once the engine swap happens.

So many decisions!!
