Small block conversion

Hi Folks new to the forum - I'm running a worked small block , turbo 700 and 9 inch in a 66 Holden which is a GM body from down under. The plan is to ditch the Holley and use a factory EFI setup with a Delco and custom tune. I'm okay with the hardware but still learning around the software so on a rapid learning curve :thumbsup:

I've done a couple with the chev tpi manifold and vn 808 ecu I'm in nz there's a base tune on pcmhacking.net for stock 350 crate engine with tpi and 24lb bluetop injectors
