Why You Need a Dyno Tune After Fitting an OTR Intake on Direct Injected Holden V6s 🔥

If you're thinking about upgrading your Holden V6 Commodore with a cold air intake, you’ve probably noticed there are plenty of options on the market.
One of the most popular — and best performing — is the Over the Radiator (OTR) intake. On both V6 and V8 platforms, OTR systems are widely regarded as the best flowing intake design thanks to their direct, unrestricted airflow path.
But here’s what many people don’t realise…
The Direct Injection Difference
If you own a Holden Commodore VE or Holden Commodore VF fitted with a direct injected V6 (LFX, LFW, LF1, LLT), you cannot safely bolt on an OTR without tuning and expect proper results.
Unlike earlier non-DI engines, these motors are far more sensitive to airflow changes.
When you install an OTR:
Airflow increases significantly
MAF calibration is affected
Fueling can become lean
Torque modelling becomes inaccurate
Without recalibration, the ECU may not correctly compensate for the added airflow.
What Happens Without a Tune?
On DI Holden V6s, running an OTR without a dyno tune can result in:
• Poor drivability
• Hesitation or surging
• Incorrect air-fuel ratios
• Reduced power gains
• Potential long-term engine risk
Some vehicles may “run” — but they won’t run correctly or safely under load.
Why a Custom Dyno Tune is Essential
A proper dyno tune allows us to:
✔ Recalibrate the MAF table
✔ Optimise fueling and ignition timing
✔ Correct torque management
✔ Improve throttle response
✔ Unlock real power and torque gains
This isn’t just about chasing numbers — it’s about making the vehicle operate safely and efficiently with the upgraded intake.
An OTR is one of the best bang-for-buck mods you can do on a DI Holden V6 — but only when paired with the correct calibration.

Thinking of fitting an OTR to your VE or VF V6? Make sure it’s done properly — intake + dyno tune together.
