Remapped by Central 20 racing with boost/speed limiter removed and rev limiter raised to 8,500rpm.
Modified fuel and timing map produces more power in the mid range and is suitable for GTR modified with pods filters, 3" zorst, upgraded intercooler, fuel pump etc.
Central 20 chip isn't glued to the system board, allowing for re-chipping with future mods should you wish and is great alternative if you don't wanna splash out for Power FC + dyno time.
When I had it in my car, it felt more responsive and came on boost little earlier. Fuel economy wasn't bad either getting around 400km+ on full tank of juice. Good AFR's as no notificable knocking.
