    I know its an old thread but seems like the answer you were looking for havent been answered. So if you are still wondering here is some answers from me as mechanic.

    The reason the maps can be easily programmed to make your engine more effecient and more powerfull have a couple of reasons.
    - the manufacturer mass produce these vehicles and engine, they dont always know where they are going from the factory, so they give them a tune that is safe allround the globe, meaning weather altitude and so on want be a breaking factor for the engine (at high altitude you have less oxygen which makes it harder to hit high power figures) also air cleanlyness can wary a lot, its better in countries with less dence population and fewer cars etc)

    - emissions, they need a software they just know will be within all standards around the globe, they dont want to have some cars needed to be pulled in on their own bill because it cant meet the standard in the US but it can in EU. Its easiest and cheapest for them just have one that fits all.

    - warrenty, they are always looking to make the most money, meaning that they aim for as few callbacks, auctions and warrenty cases as possible, if they had put 150HP and 320NM in all the cars, they have made some thoughts about what will it cost us maybe it raises the chance of a warrenty case by 1 or 2%, but that for a manufacturer is gonna be a lot of money if that engine is in 10.000.000 or more sold cars globally.

    - safety, with higher powered cars comes bigger safety requirements, better brakes suspension chasisstructure airbags and so on, easiest is again making one powerplant and drivetrain that doesnt need modifications to be accepted in one country but not in another. It costs money.

    There is probably more reasons but those are some of the common once. You can without problems get around 150HP and 310-320NM of torque on a 1,6TDI engine, Ive seen a lot with those figures here in Denmark no problems. Engines are build over engineered by a good amount (as long as its not a PSA engine) and almost any VW and Audi engine can handle around 30-40% more power without any loss in wear on parts.

    Also, with a good tuner they know the signs on an engine being pushed to hard. They look for a lot for things, inlet temp, exhaust gas temp, duty cicles, knocking, a/f ratio, charge pressure drop, engine temps, airflow and so on. An engine reaching its limits or components reaching its limits will give signs of it. So a choose a good tuner with good experience and that takes the time to make a good tune that is teste on a dyno. Pay a little extra to get someone with knowledge and not a garage tuner that havent got the means to test the things changed and doesnt have the time to raise the powerfigures in small increments.

    Just had my 1.6tdi (CAYC so 105bhp) remapped at my home by Quantum Tuning, now proudly sporting 145bhp and car is so much more responsive and eager...£249 well worth it.

    What torque now and what does your 1.6tdi do to the gallon ?

    Personally had a remap done with 'top speed remapping' and claimed 160hp/ 340nm torque. It really does feel like it.
    I did this on a 127k mile engine but also replaced cambelt..and planning on upgrading intercooler. so far so good. It would still be interesting to see how much each part can really handle.
    Mpg before remap on motorways avg 45.. after remap 50,
