Hi Juanma68, I personally seem stupidity to reschedule something that has already been studied "Factory", I don't know what you mean that it is "a little down" in the slopes, by power, of course you can reprogram, but why have those of Peugeot have done? Are they so idiots to get a car with less power than other brands? If this were reliable, think that your car would have already left with 20 or 30 hp of more, but ... if they do not ... another thing is the opinion of those who are dedicated to reprogramming and tell you what they think, I say that the brands as electronics as an electronic engineers are signed if their "science" is so good ... I do not say more. Greetings!!
