I have been hearing that the stock cycle duty is too high on our fuel pumps and then I watched a show where they moded a Sti one mod was to change the fuel pump has anyone besides matt and I hear of this.
It is a cheap mod and is walburo pump plug and play!
I have read it changes the cycle duty from 105% to 90% so when you drive hard the #3 piston doesnt run too lean!
does anyone have any more info on this
