Ummmmmmmmmm.........thats an interesting one Shouldn't really make any difference whatsoever, the relay simply switches the relay on, it doesnt vary the rate the pump works at, simply on or off?

Seems very coincidental though. I'm game for that though if that is the case because my cabriolet was doing a shocking 50 miles on £10 whether u ramped it or didnt boost at all, and my relay nearly set on fire just before i stopped using it lol
