I own a 1964 EH Holden and a 1975 VW Beetle. I have had the EH fitted with a PR14 Fuelmate for some time now. I have noticed significant improvement in torque at highway speeds along with an approximate 12% reduction in fuel consumption. Also the engine does not ping under load any more. Since recently fitting a PR12S to my VW I have noticed a similar increase in torque and reduction in fuel consumption which continues tio improve over time. I have found that both vehicles are now starting easier when cold and hot. The exhaust on both vehicles appears to be cleaner and neither vehicle now blows any sooty residue on cold start up.
