a turbo timer and boost gauge in one?

yep, and its super small, so its east mount in a low pro spot - i had mine set in front of the check engine light.

here's some info about it - http://www.nolimitmotorsport.com/bli...timer-dtt.html

can these be mounted in the vent?

im sure it could... though it wouldnt be ideal, as its a rectangle.. not a circle.

i mounted it in front of the dash and all it blocked was the check engine light..
