Hi,

I recently bought another WRX, which has a Power FC fitted. The car also came with the standard ECU which I want to fit back in, drop the boost down to standard and sell the PFC

The car has a green filter, stainless steel exhaust manifold and straight through exhaust - is it ok to run on standard mapping with these?

Cheers

Pete

 

Why? Go to the boost settings and lower it, if the car has been mapped with all these parts on I would just leave it where it is, that way if you have that option to up the boost at a later date, there are 4 boost settings you can change between, "that is if you have a Power FC commander fitted, Is it really worth swapping for what £150-£200 you would get for a second hand PFC?

 

headers and decat mean you need it to be running on the powerfc, the standard ecu map could be unsafe
