I can't seem to find any prices on base mapping

I'm looking for a base map for my 91 nx2000,

I need a map for the following

370cc injectors,
Z32 maf,
4 bar

Only question I have is once I would plug the ecu in will I have to set my timing back to stock or leave it retarted at 13?

So *** will that cost me to get that done?
