Default ECU and Tuning Question

So I am going to be starting my NA-T project this week and will be finished by Aug. 1st. But along my parts collecting and planning I still have one unanswered question. Am I going to be able to run my Stock N/A ECU safely after I boost the car? I plan on installing an SAFC-II just to kind of keep it on the safe side until I can go full Standalone (AEM V2) next year. Does anyone know how safe this is at just 8psi. I am limiting the Boost to 8psi with a controller and 38mm TiAL Wastegate with appropriate spring.. I figured an SAFC-II would be plenty capable, but im not sure. Like I said it will only be a one year MAX Temporary thing.

ehhhhh
the na ecu doesn't respond to boost well, not even with a piggy back
you should look at the tt ecu mod thread.

that would be better suited for your goals.

I love the wright up for doing the TT ECU MOD.. And would love to do it.. But I am just trying to get her down the road as I am unable to go either route right now TT Mod or AEM.. I hate putting projects on hold especially when I am so close.. Is there any piggy back that will work for the time being.. I have heard of tunning with an SAFC or FIC
