When not on the gas my boost gauge sits at like -20..then when i am at full throttle it goes up to -10..I am getting the boost..but its reading like that...is my gauge set up wrong or something? I can feel the 10psi boost, its not reading right.

 

where did you tee the vacuum line to?

 

whats wrong with whats its reading now? that seems normal to me

 

on my boost gauge its at 0 when its at an idle and everything but it will go up to 12 when im boostin

 

isnt it supposed to be at around -20 or -18 at idle. Thats at least what i remember mine being

 

yea its supposed to be at negative 20 something at idle.

 

then is mine hooked up wrong? or is that the way its supposed to be

 

it reads in the vacuum only. when he is boosting, is says hes at -10 vacuum...

 

so is it hooked up wrong?

 

i actually have no idea. I wouldn't think its hooked up wrong...Its not a difficult thing to hook up. My guess would be that your gauge is defective. Go return it and get another. Dont tell them you hooked it up though, or they may not give you a refund. Just say you decided not to use it.
