    Greddy
      60 mm p/h | 
    
    Pretty
      obvious, really.  The Greddy gauge measures boost in Bar, and vacuum
      in mmHG.  As a result, I've become fluent in converting between Bar
      and psi, and between mmHG and inHG. |

    EGT | 
    
    Greddy
      60 mm p/h | 
    
    An
      absolute must for anyone who's increasing the boost on a turbocharged or
      supercharged engine.  Generally speaking, high EGTs (exhaust gas
      temperatures) can damage an engine, and are 
    sometimes the result of lean
      a/f ratios. |

    Greddy
      60 mm p/h | 
    
    The
      Greddy gauge measures fuel pressure in Bar.  And, yet another reason
      to learn how to convert between Bar and psi. |
