hey guys my car wont boost help!

what should i do what should i check??

 

lol well this is a turbo forum so its turbo

1996 lsvtec with a t3 garret turbo custom built kit
we i drive the boost gauge goes from -20 to 0 will not boost

not sure why

 

did it ever boost?...check connections, wastegate, turbo

 

never boosted before

i have a t3 garret its new
sard racing bov welded to the intercooler(i tried it on my friends car and it worked fine)
greddy type s bov

mbc from home depot
im going to check if the wastegate has the spring in it!
i never opened it. i guess sometimes they dont have springs!

and another thing when i drive it i can hear the spool of the turbo but the boost gauge hits from -20 to zero
but i can hear the turbo! all the piping is sealed car idles fine but ill i can hear is the turbo moving!
