This is a BLITZ dual turbo timer. It came up during a garage clean-up. It can display boost pressure if connected to a boost pressure sensor. I have only confirmed the power input. Other functions are unconfirmed due to lack of a testing environment. It is a vintage item. No claims and no returns accepted. - Brand: BLITZ - Product Name: DUAL TURBO TIMER - Included Items: Wiring set (only what is pictured) - Display: Digital display Thank you for looking.
