which efi for my setup???

[Hammered]

I have the Gen7 with WB O2. The WB is a necessity in my opinion. The latest firmware of the Gen7 will let you use other vendors' WBs, but I don't think the Gen7 is setup to take two O2 inputs. Perhaps through one of the aftermarket boxes? You can always swap and check your tune bank-to-bank. That's what I'm doing.
