apexi safc? map ecu?

[west_side_supra]

ok well i currently have the apexi safc in my car, wired up ready to go. well power house just sent me a free map ecu for making me wait on my new turbo manifold so now i'm wondering if i should just go ahead and put the map ecu in, from the looks of it, alot better way to run, i've heard of people running off of manifold pressure instead of maf sensor and getting much better results, plus the map sensor will get rid of that pesky maf sensor and give me less restriction.

now for the actual questions

who has ran this?

how do you like it?

there is a steel braided hose that came with the kit and i have no clue what it is do you?

any recommendations on were to put the map sensor? location on the manifold?

will this raise my fuel cut a little higher than 18psi?

and last but not least, this removes my MAF and will have no need for the safc anymore?

and if the case is that i go with this who will buy my safc and lexus maf?
