ClampLink

 ClampLink is a simple voltage clamp designed for use where a signals level causes a cut or limit to be invoked.  The ClampLink limits the the signals level to just below the value that causes the cut or limit.

   ClampLink is primarily designed for use with Manifold Absolute Pressure (MAP) sensor signals where a fuel cut is invoked when the signal (or boost pressure) reaches a preset level.  The ClampLink prevents the ECU from ever seeing a signal above that preset level while passing all signals below that level unaltered.  This effectively removes the 'over boost fuel cut' allowing boost levels higher than factory to be run.
