considering a Lt1 t56 swap

Heck you may end up not having to tune it Idk. I have a friend with a 5.7 vortec in his 94 Silverado.I think he just dropped it in and ran it.

honestly i dont see why i would need to but every where i read theres things about the security on the LS's as well as removing the EGR codes etc for the header swap and for re-maping the fuel system if you run a aftermarket fuel system etc

Well yes you'll have to tune the LS, but the LT1 Idk.
