Potential twin turbo build, looking for injection advise

I'm also running the fitech with a single 76mm turbo. I've had some issues with it, not saying it wasn't my fault, but I have finally got it set up pretty decent I still have some tuning on it to do but so far its been a great product. I dont have the track time subcom does so he would no more about how it acts then I would I've just done some street pulls and it seems to keep the afr where you want it.
