I do have fault codes on the ECU as i was going to have the car remapped at the same place where they fitted the dump valve. They said to me, that they would have to send the ECU off to sort the
problem out. So if i take the baileys dump valve off and put a forge 007p one on instead it should clear the fault codes. The place in queation where i had the work done was performance 3000 up in yeovil, and they are well know to **** peoples cars up, if iv know b4 hand i would never set foot in the place!
