Wouldn't spend money on one myself as they are a

WASTE





OF






TIME





AND






MONEY!!!!!!!!






Any changes you make at the 'power' waste valve are detected by the standard ECU are are weaned out/opposed at the standard fuel pressure regulator thusforth you get NO BENEFIT FROM THEM unless you go standalone ECU and base your mapping around the new pressure boost regulator valve waste of money thingy!

Do yourself a favour and DON'T BOTHER!!!
