You should be paying attention to all the grief people have had when they did too many mods to the fuel injection system BEFORE they actually get it running.
Go with stock inj. and MAF for your SVT initially for the break-in process and for you first dyno run. You can have those other items ready in case you need more, but I have learned like others the hard way that you just can't plan for the future Forced Induction motor AND start running those mods when you are still running around as a NA motor.

Your stock fuel system will do a better job of tuning itself initially and you won't have to worry about running too rich or too lean on a brand new motor.
Save your money!!!!!!!!! I didn't and I have useless parts to sell!
Better yet, get an emanage and use it to do fine tuning AND evaluate whether or not you need bigger injectors and MAF because it can monitor and datalog both of those items along with other things.
eManage...I'm still making good use of mine EVEN with a custom chip. Bang for the buck.

The only thing better out there the TWEECER but it won't work on my car.
