Brad Rauch-1991 SHO As you can see, this curve shows that I was having a low end torque problem, which I have been complaining about for a few weeks.  It turns out that my actuator for the secondaries was not connected and that caused them to fail open all the time.  We fixed it in the parking lot, but I didn't get to do another run afterwards.  Still, the peak power is pretty strong for a 140,000 mile pretty much stock SHO.   View Brad's Modifications
