Caterpillar C9 remap
Pick the years that match your car. Engine choices and figures change between generations, so the 9 engines we cover are split by shape.
Which C9 do you have?
If you are unsure of the generation, the registration document gives the first registration date.

What to expect from a C9 remap
The gain comes down to the engine rather than the model, so a C9 with a small turbo diesel and one with a big petrol will read very differently. Pick your years above and then your engine, and the figures on that page are the ones that apply to your car.
We road test before and after, and anything that looks wrong on the initial read gets flagged before we write. If the car has a fault we will tell you rather than map around it.
You can see the whole Caterpillar range, or ask us about your car.
Book your C9
We write and test every file at our Aston workshop, on our own rolling road. Ring us with your reg and we will tell you what your car should make before you commit to anything.
