The SVT ECU will help me in several ways:
reduce the time to get the tune right
is set up with SVT cam info already
allow me to break the engine in without running so rich
allow me to have a chip set with SVT ECU for saling purposes
allow me and you to physically see the difference in using an SVT ECU and stock ECU via camcorder
I just think starting with a more agressive ECU will make things a little easier, but more importantly make the car a little more driveable while breaking in the new bearings.
