So you went from practicle to ls1 then back to practicle.
For a simple practicle daily just run 22 -30 lbers from bosch, NOT DENSO you dsm nut. Keep your factory intake mani, and run no more than 8psi. As for your afm do you want it before or after your turbo, thats your preference. Same with icv, to run it or not. Both of mine are in factory locations working like factory.
You need a rising rate or a stand alone manegment. which ever you like.
there are some good IC on ebay for cheap. Pick your size.
