If you are getting ALL those goodies (wideband, boost sensor, the Profec E-01!) and especially the LAPTOP CABLE, definitely use the Emanage. With the E-01 you can control the emanage up to a certain firmware (not the latest) but it is more of a pain in the ass, much like controling an Apexi PowerFC with the remote.
With the pressure sensor you can make timing and fuel map corrections by boost pressure, instead of just the limited tps% or MAF voltage parameters. You can alter fuel the same way as the SAFC and/or hook the injectors directly to add fuel.
It is indeed way more complicated than the SAFC, but beats it in every way, unless you tell me ease of use is your main concern (which I could not agree with but...). Playing with timing and fuel is better than playing with just fuel.
