my car is a classic wagon wrx 95 to jog anybodys memory and im sure this route has been taken many times,
ive decided to keep the td04 til it gives up as its in good nick
my mods will be full decat system and panel filter,
my current ecu is the 3B, i was hoping to either chip this one or replace with
a different ecu but still run the td04 but with higher boost?
is it possible to get good gain, plus ill add walbro pump for good measure?

thanks again

 

Basically the main question is about what's best to do with the ecu, chip it or get one stock from another car but must run a td04 turbo with the mods stated. Thanks....
