Toyota GR Corolla — Performance Tuning That Unleashes the Rally Spirit

The Toyota GR Corolla has already earned its place as one of the most exciting hot hatches on the market. With its turbocharged three-cylinder engine, all-wheel-drive system, and rally-bred DNA, it delivers serious performance straight from the showroom. But as always, there’s more potential beneath the surface — and that’s exactly what we unlocked for John Cavill from Titirangi, Auckland.

John wanted a calibration that would bring his GR Corolla fully to life. After a complete tuning session at AutoUpgrades, the results spoke for themselves.

“Just had my '24 GR Corolla with Lars at Auto Upgrades... astounding result!! It wasn’t just the 50 hp and 70 Nm of torque that I gained (which is pretty bloody cool I admit), but as much as anything it was dealing with Lars and the considered advice he gave me. No dumb upselling, just good advice and an amazing result. Cannot recommend Auto Upgrades enough... many thanks Lars!! Stoked…” – John Cavill, Titirangi (Auckland)

That’s the kind of feedback we love — real results, felt on the road. The GR Corolla’s G16E-GTS engine is already lively, but with an additional +50 hp and +70 Nm, it becomes something genuinely special. Acceleration sharpens, mid-range torque fills out, and every gear change feels more purposeful.

Why the GR Corolla Responds So Well to Tuning

The GR Corolla’s three-cylinder turbo engine was built for motorsport durability. Toyota’s factory calibration, however, is intentionally conservative — tuned to meet worldwide emissions and fuel-grade standards. By carefully optimising fuelling, boost control, ignition timing, and torque management, we unlock the hidden performance while maintaining OEM-grade safety margins and drivability.

Corolla Performance Gains Across the Range

While the GR Corolla is the star of the show, every Corolla benefits from professional calibration. Here’s what each model typically gains when tuned with precision:

  • GR Corolla: +50 hp, +70 Nm – transforms from hot hatch to genuine giant-killer.
  • 2.2 D: +40 hp, +80 Nm – effortless torque for towing or touring.
  • 2.0 D: +40 hp, +80 Nm – stronger mid-range for motorway overtakes.
  • 1.8 D: +25 hp, +50 Nm – smoother, quieter pulling power.
  • 1.6 P: +10 hp, +15 Nm – sharper throttle, quicker response.
  • 1.8 P: +10 hp, +12 Nm – refined and flexible around town.
  • 2.0 P: +10 hp, +12 Nm – added depth through the rev range.
  • 1.5 P: +8 hp, +10 Nm – lighter, livelier city driving.
  • 1.3 P: +9 hp, +11 Nm – transforms the smallest engines into eager companions.

Tuning gives every Corolla a renewed sense of purpose — more response, smoother delivery, and a drive that feels far more alive than stock.

Customer Experience Matters

As John mentioned, it’s not just about dyno figures. It’s about process, trust, and engineering precision. We take time to understand each driver’s goals before applying the same calibration discipline used at OEM level — no upselling, no shortcuts, just clarity and measurable results.

Unlock the Potential of Your Toyota

If you own a GR Corolla — or any Toyota that deserves to perform at its best — professional tuning brings out the depth of engineering Toyota built into it. Expect sharper throttle response, stronger torque, and smoother power delivery across the board.
