I have a 98 V70R ...yesterday i installed a boost gauge to get an idea on how the car was running .I took it for a drive arounf the block and didnt have any boost. So after double checking my connections i took it to a hill on the freeway and really got on it..I only got about 1 psi worth of boost.so today after looking at the line i had tapped into it needed replaced . So i replaced it. I took it again on a hill on the freeway and after i had gotten up to 65 mph i mashed on it . I hit 4k and it still only hit 5 psi . The other hoses are not that bad but will be getting replaced in a week or so. Any ideas? thanks in advance .
