Ive had my heart set on getting a dashhawk for a while now. After doing a little research ive found some boost guages for like under 40 bucks (mechanical). I think I would rather save a 200 bucks and get the cheap one instead of the dashhawk. Ive also seen some very expensive 100 dollar boost guages. Dont really see a difference other than they look nicer. Anyone have any trouble with the cheap mechanical boost guages? Thx for any help.
