Mate you get what you pay for, If your wanting to do performance and gain those numbers aswell as features Syvecs is they way as you saw in my new thread.
Not only the fact that Syvecs mapped by Ryan is responsible for me now owning one of the most powerful BPU's Supra but one of the most geared up Supras with knock sensor, advanced traction control by the twist of a knob, wideband sensor so the ECU will always be reading my fuel/air mixture and constantly adjusting it to get perfect performance but the JTI screen with all my read outs, calibration settings. I can even set a pin so my car wont start unless you know the pin! Now thats sci-fi stuff!!
Save the money and get the best, or you will always look back and think "should have I gone Syvecs?"
