So for the initial setup I know that before I do anything, I need to go to settings and do the INT ALL to reset all factory defaults. Then go and set my maf, and my injector correction. Alot of people say to use the base maps that are posted on enthalpy's site, instead of apex'i preloaded maps.

This is where I get confused a little, with the power fc, I know that it will automatically adjust the preloaded maps for the larger injectors, but when I change the map do I need to go back through the entire map and correct it for the injectors or does the pfc do all that? And how safe will it be to do some street tuning on enthalpy's suggested base map? I don't want to go out and detonate real bad, or be way too lean and BOOM there goes all that work. Is the base map just going to let me put to a dyno and get everything done, or will I actually be able to get into boost and do some street tune before the dyno, so I can save some money and not be on the dyno for 5 hours. I have an Innovate LC-1 wired up to the datalogit so I will be able to log my afr through the pfc map, but just wanted to make sure this would be safe. Any suggestions/help from experience would be appreciated. I've done some slight tuning, but that was just with a safc, I think I got pretty good at that, but that wouldn't be able to run with the new mods.

Also what would be a safe rev limit for this setup?

Oh, here are the specs:
S13 redtop
Stock bottom end
BC 264s, springs, retainers
Greddy RAS
DW 740cc inj
Walbro 255
Treadstone T3 topmount mani
Stock intake mani
T3/T4 50 trim .48 exh
Tial 38mm WG .9bar spring, I also have a 1 bar spring, don't know which to run.

dammm looks like we are on the same problem
