    What are the benefits of modifying ECU program (ECU upgrade) or do any harm?
    In general, the power increase 8% -36%, lower fuel consumption by 5%-25%, reduce emissions.
    A. naturally aspirated models can increase horsepower 10%;
    B.TURBO models can increase horsepower 20% -30% or even more;
    C. shift more smoothly, the power of convergence even better;
    D. solve many problem which the original can not resolved, such as the: low speed easy to turn off and the transmission shift shock etc.

    Hmmm, this sounds a bit like an advert to me. Absolutely no, you'll not see anything like a 10% increase with re-mapping a normally aspirated Ferrari.

    On the 360/430 mostly you'll just hope to gain a bit more throttle response [its software configured] and a few extra bhp when combined with other upgrades such as a free flowing sport exhaust, cats and possibly manifold/headers too. Nothing too drastic unless you spend big $ and start looking at supercharging and other things such as larger throttle bodies, air flow meters and airbox design. Excluding the supercharging option it still won't be huge gains but you will get a much louder car and once tuned its harder to re-sell. Want more power? Reduce weight instead or simply buy a different model. On the mods route its actually far easier to accomplish weight reduction and achieves the same thing, an improved power to weight ratio which in turn improves handling [provided you corner weight your car later].
