2.0 liter map whats the best way to make a base one?

ok, basically im just wondering whats the best way to scale a map. For example say a 2.0 gsr motor built for N/A. would it be best to just use the injector multiplier and change the discplacment?

I always start out with the JDM P30 maps. Then scale it for injectors, fuel pressure and displacement. Don't change the injector multiplier, fuel pressue, and displacement ntil after you've created the map. And add boost tables. You can choose how much timing to pull per psi or just go with the default. The default seems to be alot. If I can remember I usually go with pulling 0.75 degrees of timing per pound.
