Mack Remapping Service

A Mack that holds its speed on a hill gets the load there sooner and spends less time grinding through the gears. We remap Mack's MP engines and the older ones before them as part of our truck remapping, with a map written in-house for your engine.

Why Remap Your Mack?

Mack belongs to the Volvo Group, and its MP engines are close relations of the ones in the Volvo trucks we remap. On a heavy American truck, the gain you feel first is torque low down: it pulls a higher gear with a full load, drops fewer gears on long drags and uses less diesel doing it. If fuel is the bigger worry, our economy remapping leans the map that way.

Mack Diesel Tuning

The calculator lists 9 versions of the 12 litre MP8. The MP8-485M makes 492hp and 2305Nm as standard and a typical 562hp and 2598Nm at Stage 1. That's for a truck in good health, so yours gets checked over before the map goes on.

When you ring, tell us the engine, the mileage, what the truck usually pulls and whether any warning lights are on. That's enough for us to tell you what a remap will do before the truck loses a day off the road.

Check your engine in the calculator above, or ring us on 087 744 2633 to talk through a Mack, or a mixed fleet with MAN trucks in it.

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
