Power FC PFC advice

PFC advice
Hi everyone,
So I took the opportunity over the summer to take the engine out to replace the original 100k miles twin turbochargers with another set of twin turbos (used), new heat shields, ACV and air pump removal, etc. I also picked up a PFC and DataLogit, wideband, water injection, 1300cc Secondaries, and fuel pressure sensor....however the summer got away with me with the family trips and activites - and I have a track event in a few weeks. It's now crunch time for me so I'm considering just installing the engine with the 1300cc, PFC, and maybe the Datalogit. My question is how difficult would it be for me to tune the car with just this setup? Is it just adjusting the map to take account the 1300 secondaries? Or would I need to have the wideband and fuel pressure sensor to take full advantage of PFC? I have access to a Dynapak if that is a variable in helping with your advice.
Other mods are HKS open intake, exhaust, downpipe and a high flow cat (probably toast).
I have to complete the next two events and can easily pull the engine again over the winter. Or do I just go with my stock 850's and stock ECU?
Thanks in advance.

I'm leaning toward putting the stock 850's and ECU in just to ensure the used turbos and the sequential system is functioning (and that I put everything back together correctly).
Also will give me more time to read up.
Thanks.

I already pulled the pins in the harness and have a 1/4 turn on the idle adjust when I tested the used PFC before taking the engine out - what are your thoughts on using the PFC and bas emap with the stock injectors (550/850), and my current setup of intake, exhaust, high flow cat (still have stock intercooler)?

It Just Feels Right

and FWIW, i have a PFC with stock twins, emissions (at least what's left), and a large street port and it ran like **** on a base map. I assume it was the porting, but i still wouldn't trust a base map on a track
Also, you may want to look into upgrading your SMIC before you get your car tuned. The stock IC is inadequate. Or, at least look into AI
