GT-R R35 — Stage 2 ECU Tune
- Sharper throttle response
- Quicker turbo spool
- Stronger midrange power delivery
- Consistent boost holding
- Maintained factory drivability and safety
- Improved exhaust note
This 2008 R35 came through for a proper Stage 2 calibration after the owner fitted a high-flow intake, upgraded downpipes, midpipe and full cat-back exhaust. Wastegate upgrades and a new boost control solenoid were added to improve response and manage cylinder pressure more effectively through the mid-range.
The VR38DETT responded well to the hardware changes. On 98 RON it recorded 348.6 kW at the wheels with 618 Nm of torque, a solid improvement over factory output without venturing into the territory that demands built internals. The same car also runs a flex-fuel calibration, which is recorded as a separate result. The calibration focused on dialling in fuelling and ignition timing to suit the freer-flowing exhaust and improved boost control, keeping delivery smooth and predictable for closed-circuit use.
Is this level of output safe on the stock VR38DETT block and internals?
348.6 kW at the wheels sits within the safety envelope of the factory block, pistons and rods when calibration and fuelling are done properly.
What's the main benefit of the wastegate upgrades on a Stage 2 R35?
Upgraded wastegates improve boost stability and response, particularly in the mid-range. They allow finer control over cylinder pressure and reduce the risk of unintended overboost under varying load.
Does this tune require E85 or will it run on 98 RON?
This run was on 98 RON. The same car also carries a flex-fuel calibration, recorded separately, which makes more power on ethanol.
This calibration was developed for a workshop like yours
The Nissan GT-R above was calibrated by Protunes for a partner workshop — they did the vehicle work and kept their customer; we did the calibration engineering on the ECUTEK. Add professional ECU and TCU calibration to your workshop without employing a calibration engineer.
