to all bimmer owners: I have a neighbor who is a syntek rep which markets Engine Boost 2.0 that claims: 1. Increase Fuel Mileage, 2. Prolonged Engine Life, 3. Improved Performance, 4. Reduced Harmful Emissions. I have an E30 with 290K which has served me well. But before I test it I wanted to get feedback from NCC bimmer community. Please reply. Thank
