Todays auction is for a good used R32 Skyline GTS-T ecu tuned professionally by Tomei Enterprises from japan. This ecu has a higher rev limit, no speed limiter, better fuel and ignition maps, VG30 upgraded turbo and boost up. I have personally ran this ecu for 3 months and it is a huge difference over stock. This will allow your RB20 to hit power faster and pull harder for longer safely. I bought this unit for $550 2 months ago but I upgraded again. Feel free to email with questions. Thanks.
