Hi all ........I'm after a v4 sti ecu which I'm finding hard to get as there a loads of wrx's and v3's . my mechanic has told me it has to be from a v4 not a v3 sti . I was going for the re mappable ecu but that above my budget for now ..... My car started out as a uk 98 turbo 2000 wagon since then i brought a red top sti engine frm denners on this site it has a front mount intercooler , walbro 255 fuel pump ,orange maf, vf 28 turbo ,4 pot calipers ,sti rear tailgate and interior ,been lowered 40mm just need ecu now and would like to know what bhp would i be running
