Hi all I've got a MY94 WRX and been looking at getting a bit more power out of it want around 280-300. I have been told I can't just get it remapped and that I need a whole new ECU. Had a quick look around the internet and seen a few mentions about a 6k Ecu which I think is from a V2 Sti and would push it up to 280bhp1? Is this true and is it just a straight swap or is there a lot more to it ? Thanks in advance
