i am taking the old BDS 8-71 off because it is not as efficient as thay said it would be[understatement!!!]i overdrove the BDS to 14% ove nd only got 10lbs of boost from the old 5%over and 8lbs.i got a whole lot of heat to go with it and the car slowed from the heat.i did try some fuel/timing changes but thay did not help.
i am getting a new blower shop teflon stripped 8-71 to replace the BDS.
