Every map dyno-certified
Master Tuners, Not Slave Tuners

Every tune is developed in house. No locked or resold maps we can't change.

Plenty of outfits just resell generic files they can't open or change. We don't. With 14 years and thousands of tunes behind us, we know these engines well enough to build a tune specific to your vehicle, and stand behind it.

That control is the whole difference. It's why the gains are real, repeatable and safe.

Built For Out There

From the highway to the high country.

Towing the van, loaded for a weekend away, or just the daily grind, your tune is built around how you actually drive your vehicle out here. Not a number chased on a lab bench.

The Difference

You'll wonder why you waited

The numbers our customers feel every day, measured on the dyno, not promised in a brochure.

20–30%

Power & Torque

Typical increase on a completely stock vehicle with no supporting mods. More grunt right where you use it.

0lag

Drivability

Linear, responsive throttle. Smoother acceleration, easier overtakes, no more dropping gears on every hill.

↑15%

Fuel Economy

Up to 15% better economy, especially towing and on the highway, where it pays for itself fastest.

How It Works

A remap, not a band-aid

There's a real difference between changing how the ECU (your Engine Control Unit) actually runs the engine, and just faking the sensor signals that pass between the ECU and the engine.

ECU RemapInside the ECU

Inside the ECU

We rewrite the tuning tables inside your factory Engine Control Unit, so the computer that already runs your engine simply runs it better.

  • Rewrites fuel, timing, boost and more, at the source
  • All factory safety systems stay fully active
  • Custom-built per vehicle and dyno-verified
  • No extra hardware to fail
Piggyback ModuleBolted on the side

Bolted on the side

Chips, throttle controllers and plug-in boxes sit in between the ECU and the engine and modify sensor signals to trick the ECU/Engine, a fraction of what a remap can do.

  • Only alters sensor signals, not the tune
  • Can't touch the core ECU tables
  • Generic box, not built for your engine
  • Extra wiring & hardware that can fail
  • Throttle controllers do nothing for real performance.

What owners say after a week

Real reviews from customers — sceptics included — who felt it the moment they drove it.

★★★★★

I was always sceptical about mail-order tunes, but a week in it's honestly like a different car. I've got genuine confidence to overtake while towing the camper now.

Conor SchofieldMail tune
★★★★★

Best mod I've done. No more switching the AC off to get up a hill or overtake. So much more torque.

Matthew HammondStage 1
★★★★★

Why did I take so long. My D22 ZD30 is so much more drivable. Power increase is very noticeable and it's a pleasure to cruise the highway now. Massive thanks to Jamie and the team.

Regan PownallNissan Navara D22
★★★★★

Words can't describe how much better the car is, mind blowing. Best money I've spent on the car, maybe on anything.

Jacob MartinDyno tune
★★★★★

Huge improvement in throttle response and power delivery. The extra torque is very noticeable towing, and I'm seeing 5–10% better economy so far. Do yourself a favour.

Shane CaleTow rig
★★★★★

10/10 for professionalism. Gone from struggling uphill to cruising up a breeze. Best advancement I've done.
