No turbo, but I'm not after bhp gains, more after the better fuel economy.
As per Colm - by the time you've paid for the ECU and/or mapping - you'd never make the money back on the fairly minimal increase in economy. Aftermarket ECU's (either piggyback or full EMS) are more about getting the fueling right on a modded car and getting reliable power - I'm sure the standard ECU will do just fine on your FTO unless you start to go outside the parameters of air/fuel/timing etc brought on by extensive modding such as exhaust + decats + induction + increased volume plenum + fuel pump + Fuel pressure regulator + larger injectors etc etc or Forced induction (turbo or supercharged).
If you are looking to increase economy then loose weight from the FTO (spare wheel/excess trim) or both efficency and weight -e.g. - remove air con (reduce load on engine and reduce weight) or use decats (standard cats are very heavy and inefficent).
Or just adjust your driving style - early shift - minimal braking (keep good distance to car in front) - low rolling resistance tyres etc etc,
