If your car has EU3Mems there are places to do this. I had my 2001 1.8k roadsport remapped by Kmaps following fitment of 633 cams and verniers by DVA and a Powerspeed 421 manifold/exhaust. Simple and inexpensive process with Kmaps, the above work transformed the cars drivability, efficiency, and level of fun. I believe with Revilla's work, you can do the mapping yourself, or likely find others to do it for you. I'm not sure the Rover Mems is suited to fitment of throttle bodies.
