i have recently joined the scooby club by purchasing myself a beautiful 93 WRX, but i have a few questions which i hope somebody will be able to answer for me.
1. what should the boost be set at? i've heard it should be around 12-15psi for standard. its currently at around 9psi (according to the boost gauge), but it has a bleed valve so can be increased if necessary.
2. is it possible for the standard ecu to get re-mapped? or do i need to invest in an uprated one? wheres the best place for this to be done locally?
3. or is there a better engine mod i could do before a re-map?
any guidance you are able to give me is most welcome.
its only got a few minor engine mods; a full de-cat HKS exhaust with a HKS induction kit.
