Help with MAF vs MAP and DBW

Ive bought myself a LQ4 block which i plan on putting into my 85 Z28.

I'm trying to gather parts for my swap right now. Based on reviews, reading the forum, etc... I think im going to be going with a TSP 228R cam, 112lsa.

My question is, do i run this MAF or MAP.... Or both? Not 100% sure of the PCM operations of an LS.

A local seller in my area has this for sale for $1000

Painless Performance 60221 Harness Kit (NEW in the box)
OEM ECM (computer) for this harness (flashed already to remove the security lock out)
OEM DBW Throttle Body (3 bolt mount)
OEM DBW Throttle Pedal & Mount
OEM TAC Module for Throttle Pedal
Transdapt Throttle Body Extension (increase performance)
Street & Performance Billet MAF/Air Filter Combo (NEW)

I know this is a good deal. But is DBW a 58x thing? My engine is a 24x wheel, and would DBW be ideal for my swap?

Stock ECU will work best with both.

You would need both for the stock ECU/PCM... if you do a Speed Density Tune, then you can do away with the MAF.

Agreed with above, you want to use MAF and MAP in a relatively stock application.

Question, Does the kit come with the TAC Module Harness? Make sure this is a Green/Blue Harness.
