Got my Ranger PX2 tuned here. Massive difference in throttle response and pulls way harder up hills with the caravan. Workshop is spotless and the lads explain everything. Worth every cent.

Booked online, dropped the car off in the morning, picked it up after work. Honest quote, no upsell, and the difference in my Q5 is night and day on the freeway.

Drove down from the Central Coast for these guys and it was worth every km. Smoother, stronger, and using less fuel on my run home. Highly recommend to anyone with a diesel.

Had my LandCruiser 200 Series tuned. Completely transformed — towing my horse float is effortless now. These guys know diesels inside out. Factory file backed up, zero risk.

BMW X5 30d done. Was nervous about voiding warranty but they explained everything, backed up the original file, and the result on the freeway is outstanding. Fuel economy actually improved.

My D-Max had a DPF and remap done the same day. No drama, no upsell, dyno sheets handed over when I picked up. The before/after numbers speak for themselves.

On the day

What to expect

  1. 01

    Drop off

    Bring your car to 591 Gardeners Road, Mascot. We'll confirm the job spec and check the car over before we start anything.

  2. 02

    Backup

    We read and back up your factory ECU file before any changes. Your original calibration is always safe and restorable.

  3. 03

    Dyno session

    Your car goes on our Mainline dyno. We tune and verify against measured power output — not off a laptop in the car park.

  4. 04

    Collect

    Pick up the same afternoon with a before/after dyno sheet in hand. Most sessions wrap up in 4–6 hours.
