Those powerbox only deliver 80% of the power they say they will, all goes in the right direction though! With ECU Remapping, it is undetectable even by dealers as you cannot save off the data to analyse it you can only overwrite it on Euro 2 systems. The newer Euro 3 you can read it off but then you need the original file to compare it against to see if it has been changed but then they wont have the original file that came with your car. Warranty is not affected and insurance is really up to conscience. I am NOT advising you not to tel the insurance company though.
Lester P, JTD80 is that the Punto? We have one of those as a Demo car - well it my hack as well, fancy having a try in it and compare it to the powerbox - it would be good to see what we both think of the two approaches. Whereabouts in th eUK are you and we will see if we can meet up
