Hi all.
I have fitted to my 1993 wrx import

Pipercross induction kit
Baileys dump vale atmos thing
5 inch ninja back box
Magnex centre de cat (3 inch i think)
Magnex 3 inch twin dump down pipe (fitting next week)
1995 ecu ( on order, here next week)
Running on optimax and millers

What should my gains be over standard 93 wrx import (240)
Should i tweak/change anything for a better gain?

Also looking to get a knock link.
Which one and how much?

Thanks everyone

Johnny
