What would your car actually gain?

Put your registration in and we'll come back with the real figures for your engine. Not a range, not a percentage from a brochure.

Why we ask for the reg

Because gains are specific to the engine, not the badge on the back. Two cars from the same range, same year, same trim, can want completely different files and produce completely different numbers.

 

Your registration tells us the exact engine, gearbox and ECU version, which is the only way to give you a figure that means anything.
