Turbo Engines engines rely heavily on computer controlled Engine_management Control Unit [ECU].
Basically the engine has an array of sensors which monitor lots of things such as throttle position, crank position, airflow etc. These signals are sent to the ECU, which processes the information received to give the best engine performance for any given driving condition.
ECU remapping can alter engine performance for higher output and/or for better fuel consumption, nevertheless be extra careful even if the tuner a top programmer.
There are many tuners offering what seem like custom ECU remapping. Most of these tuners use and alter programs that are cheaply available through the internet or other sources and are not ngam with the car engine requirements. These can actually damage the turbo/engine.
Remaping alone may not be adequate for the upgrade. Get a professional to do the job and you must get ready to spend on hardware upgrade as well - without which you will need to spend more money on repair bills later.
For performance you will probably reprogram the ECU to control ignition timing advance, force more fuel and more air into the combustion chambers, and make the turbo overspin and hold on to higher pressure than the turbo unit/system can handle and delay/never let the BOV open, which will ultimately damage it. Solution - get a better turbo system before remapping!
For fuel economy and power - if you are familiar with nitro-methane RCM car engines you will know what to do at the expense of engine overheating, simply make the air-fuel mixture lean. The same applies to EP6DT engines. Go on reprogram the ECU at your own risk and save money on fuel to partially pay for the damage later on.
For instance, PSA produces different EP6DT engine outputs [140THP, 150THP, 156THP, 175THP, 200THP....] based on similar engine but for each output there is not just the difference in ECU program but the turbo system and other hardware are unique .
Btw, even a stock Pug 308 THP140 is capable of hitting 100km/hr in around 9 secs, 1000m standing in less than 30sec, top speed more than 200km/hr .... still not enough for a 1.6liter family hatch?
Think about it! Again and again.
