Great Wall Remapping Service

Great Wall pick-ups and SUVs are built to work, and a remap takes away the flat spots that make them feel slow with a load on. The map is written in-house for your engine.

Figures from our Remap Calculator. Your own car is measured on our 4WD dyno on the day.

Why Remap Your Great Wall?

On the Steed and P-Series pick-ups, what counts is better pulling with a load in the back, so a remap that adds torque low down matters more than top-end power. For the Haval and Tank 300 SUVs, SUV remapping gives smoother overtaking, and if you mainly want to spend less at the pump, an economy remap is set up for that instead. Pick-ups used for work are covered by our commercial van remapping too.

Great Wall Petrol Engine Tuning

The Haval H6 2.0T makes 194hp and 314Nm as standard. Our Remap Calculator shows a typical 225hp and 335Nm at Stage 1. That's typical for a vehicle in good health, and 4x4 models go on our 4WD dyno with every wheel driving.

Great Wall Diesel Tuning

For the diesel pick-ups and SUVs, pick your model in the calculator above to see the figures it lists for your engine.

Pick your Great Wall in the calculator above, or ring 087 744 2633 and tell us what it tows or carries.

What happens on the day

Check your Great Wall in the Remap Calculator or give us a call, then book it in. On the day it goes on our 4WD dyno for a before run, the map is written for your engine, and an after run shows you the difference in power and torque.

If your Great Wall is an automatic, ask us about a gearbox (TCU) remap on the same visit.

So I got a hybrid turbo from muchboost installed in my Mercedes c220 and was advised to get a custom remap on a dyno so I contacted John got it booked in and he also offered hydro clean as an option and It was worth every penny I couldn’t believe the difference it made plenty of power and ticking over like a dream thanks again
