Go with the SAFC warz. I gained 15rwkw from it along. Read my BMT Dyno Tune thread in Vic. Your mods are exactly same as mine, auto, 3" turbo back zorst, hiflow panel filter.. set to 11 psi. You are looking at $350 for safc blue screen and about $120 - $150 for the apexi unit tune + dyno and don't count on 60rwkw just safc that is, if your car is in good condition
