can the stock ECU handle boost? not like 5 PSI or anything but 1-2psi from a super charger (steady no spikes)
I am close to getting:

Eaton M62
WRX intercooler
12:1 FMU ( ups fuel pressure depending on vacuum/boost)
sti fuel pump
WRX bov

with the stock pulley, the SC will only make 2 psi before the pressure drop in the intercooler,
my big question is will the ecu freak out from having the super charger on there at such a low psi?

Yup, it can, but it can't be tuned easily. You'll need to look at investing in a piggyback at some point.

good the fmu will be my short term "tuning" i am saving for the smaller pully on the eaton and an emanage ultimate so it can be tuned properly for larger amounts of boost ~12psi the ring lands on the na pistons dont like knock so it will need to be a conservitive tune
