Finding your engine
The engine size is on your V5C, and most cars carry the badge on the boot lid. Where a model was sold with several power outputs of the same engine, they are listed separately above because the files and the gains are different.
Get it wrong and nothing is lost. We check the engine against the car before we write anything to it.
Book your MT
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.
