Manufacturers info:

The Blitz DTT X timer is both a traditional manual timer and an auto timer. The Blitz DTT X auto timer mode is dependent on a vehicle boost pressure. The longer the vehicle operates in boost, the more time will be added to auto timer mode. The DTT X also offers a built in boost gauge and peak hold display. The boost gauge will show real time digital boost and vacuum readings in hKpa. The peak hold display will show the highest boost levels reached. An audible and visual warning is also built in. The warning is built in to warn the user if boost levels are above the desired levels. When the warning is triggered, the screen will turn red and a beeping sound will be heard. The user can also personalize the background color of the screen. The color can be set to red, orange, or green.
