The Mark 3 ECU can, with some expertise, be re-programmed to provide a significant gain in horsepower, which would not be in the best interests of our aims.

A full copy of rules and regulations can be found in the MSA Blue book which can be accessed on line at however the crucial area of technical regulations pertaining to the MX Register are laid out below;
