Why custom tuning instead of a flash tune?

A flash tune is a generic map written for a hypothetical car. We build yours from scratch on our dyno, watching live data on your specific engine, fuel, and condition. The numbers come out higher and the car drives better, because the map is for your car, not someone's average.

What does the ECU tune actually change?

Boost, fuelling, ignition timing, and throttle mapping. The VR38DETT runs conservative from factory to handle global fuel quality variation. With a known fuel in the tank, we open it up safely.

What does the TCU tune do?

The GR6 gearbox has its own computer, and the factory calibration is built for smoothness, not pace. The TCU tune sharpens shift speed, firms up clutch engagement, and sets up launch control properly. It's the half of the car most tunes never touch.

My R35 came with someone else's tune. Is that a problem?

Only if it doesn't match the car. Sellers often pull the mods before a sale and leave the tune in, so the map expects parts that aren't there anymore. We read the ECU and TCU, check what's fitted, and tune to match.

98 RON or E85 — which do I pick?

Whichever you'll actually run. 98 is everywhere. E85 makes more power but you need a pump near you. We map for one fuel — switching between both automatically needs flex fuel hardware and the upgraded fuel system from Stage 2+.

How long will my car be with you?

Same day or overnight. Tune on the dyno, road test, hand back with sheets.
