Stage 3 tuning for your Toyota Hi-Ace
Stage 3 is not a fixed package or an off-the-shelf power figure. It is a custom engineering and calibration project built around this exact Hi-Ace 2006 powertrain, the hardware fitted, its condition and how you intend to use it.

Before any Stage 3+ tuning
Every vehicle starts with a dyno diagnostic session
Before we agree to carry out any Stage 3 or above tuning, we need to examine the vehicle and understand what we are working with. This session lets us assess the car, review its ECU software and existing calibration, and decide whether the project is ready to tune safely.
- Examine the vehicle, its condition and the performance hardware currently fitted.
- Inspect the ECU software, existing map and available data for signs of previous tuning or limitations.
- Determine whether we can help now or whether additional modifications or repairs are required first.
You leave with a clear next step: confirmation that we can proceed, a list of changes needed before tuning, or an honest explanation if the proposed project is not something we can support.
Hardware we can calibrate around
Typical Stage 3 and above upgrades
The final specification varies by vehicle. We review the upgrades as one complete system rather than treating each part in isolation.
Fuelling upgrades
Injectors, high- and low-pressure fuel pumps, fuel rails, alternative fuels and flex-fuel hardware.
Airflow & cooling
Intakes, exhaust systems, intercoolers, charge cooling and thermal-management improvements.
Engine & valvetrain
Camshafts, built engines, strengthened internals, compression changes and unusual conversion work.
ECU & sensor changes
Standalone management, ECU swaps, MAP and MAF sensor scaling, and custom control strategies.
Drivetrain integration
Torque management, gearbox calibration and power-delivery choices matched to the intended use.
How the process works
Assessment before quotation and calibration
- Dyno diagnosticWe inspect the vehicle, software, data and current specification.
- Feasibility reviewWe confirm what is supportable and identify any repairs or hardware still required.
- Project plan & quoteOnce the scope is known, we agree the work, intended use and realistic objectives.
- Custom calibrationThe vehicle is tuned and tested around the completed, verified hardware package.
This guidance is tied to your selected vehicle
We will assess the exact powertrain and software fitted before recommending a Stage 3 or above project.
