01/02 s10 CC ls swap tunning
 

Hello all
For the specs I have a 2002 s10 crew cab that has the 4.3l v6 in it. I am looking to do a 5.3l ls swap in the futer. The ECM appears to be the 0411 that's the same as ls1 set ups.

Now for my question
Would I be able to buy tunning software like ls1 edit or similar to tune the 4.3l v6 for now then down the road change the tune and add wiring ( 2 more injectors, coil packs, ect.) for a 5.3l?
