The ONLY effect this has is to improve gas mileage. There's no noticable effect on torque or HP. Many people drive their FI cars for years with bad diaphrams and never notice the difference. This is one of the reasons that I keep a log of my gas mileage. On these cars, any advance due to the vac adv goes away as soon as you give the car significant throttle, so it's really inactive except when cruising. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------ To unsubscribe, E-mail to: <type3-off@vwtype3.org> For more help, see http://vwtype3.org/list/
