If I remember correctly, you have everything you need, if its a 24 rel engine and rear cam sensor-is it a used kit, $1400 is a good deal if it has the main harness, and the LS1 harness
the 558-400 is for the 4 input/outputs, loose ends to wire to what you want

Holley has been working great for me. Its really nice to have a wideband, boost controller, two step, overboost protection, etc all in one box. Comes out cheaper then a stock ECM once you add it all up.
$100? Poke around enough and its $60 shipped and comes with enough wire to circle a car twice.

This EMS has all the features you ask about and more.
One such is "on board" MAP and BARO sensors, two separate sensors, used 100% of the time required for Off Road Racing.
Would you like more information, pricing is equal ?

all of them work
mostly boils down to who do you know that can help you
do local reputable tuners tune/support what you want to use
do you have the time to learn how to tune it if none of the above?
i feel like those are even larger than functionality and price

Could not have said it better myself. I agree 100%.
