Cummins Remapping Service

Cummins diesels turn up in trucks, buses, coaches, pick-ups and machinery, and a remap gets more work out of the same engine whatever it's bolted into. Our truck remapping starts with the engine and then the job it does, from a coach on a long tour to a tipper on short, heavy runs.

What a Stage 1 remap does for popular Cummins trucks

Cummins ISB 260 6.7LI · Diesel

Open in calculator: Cummins ISB 260 6.7L

Figures from our Remap Calculator, for a standard engine in good health.

Why Remap Your Cummins?

A coach operator wants a smooth, strong pull on the hills with a full load of passengers, and a haulier wants fewer gear changes and a smaller diesel bill. More torque at working revs gives both, and our economy remapping leans the map towards fuel when that's the priority.

If your Cummins sits in a Dodge Ram, its 6.7 litre diesel is listed under Dodge in the calculator. We remap Detroit Diesel engines too.

Cummins Diesel Tuning

The 6.7 litre ISB and the ISC suit buses, coaches and medium trucks, while the 15 litre ISX and QSX do the heavy work in long-haul trucks and big machinery. At Stage 1, the calculator shows:

  • ISB 6.7 (325): 327 hp and 1,017 Nm as standard, 367 hp and 1,117 Nm at Stage 1
  • ISX 15 (500): 502 hp and 2,244 Nm as standard, 582 hp and 2,490 Nm at Stage 1

Treat those as typical for an engine in good health. The result on yours depends on its condition and hours.

Look up your engine in the Remap Calculator, or ring 087 744 2633 with the engine details and book your remap from there.
