okay well have been thinking about changing my ecu out in my v3 gf8 , mods done so far are, full 3inch exhaust from turbo back, ( 1 resonator in mid) external wastegate, yellow injectors , tdo4 , bigger sti top mount ,runs 12 psi daily , thinking on putting a 6s ecu in it, from what iv gathered this will raise boost to 18 psi? and has more of an aggressive tune? thoughts?
Cheers
