It's a simple ECU remaping to a 1.9 130bhp Seat Ibiza with only the turbo and IC modded.
So, using maths is something like almost 100 bhp MORE than the original car's horsepower. Quite impressive this MB Power portuguese guys with their electronic magics huh? ;)
I found this video at Metacafe. It's a Fifth Gear show review of the amazing 2007 Audi RS4 V8 that has an amazing 414bhp. They test the car against the BMW M3 in straight line, drifting and in track.. Final results? Check it for yourself here... I would want one of each :p How about you? Would you prefer the 4 wheel drive over 400 bhp Audi RS4 or the drift machine 343bhp BMW M3?
