i have a greddy electronic boost guage but it not working properly so i wanna replace it with a cheap(under 100) mechanical guage. what do u think i should get ? anything other then the autometer ultralite series tho haha. I was looking at the VDOs and they seem to be pretty good and cheap, they are also used on bimmers so im guessing they are of good quality and will match the red msp gauges.
