Hi everyone
I have read a number of threads about remapping but wondered if anyone has hands-on experience of chip boxes for the 1.9JTDm engine?
As it will be allegedly used on an allegedly new car, (allegedly), the idea of whipping it off prior to servicing and maintenance is quite appealing. (Hangs head in shame)

I like the idea of an extra 25/30 bhp without detonating the engine.
Anyone actually bought a Pbox or similar?
Mike
