alright I got a drag III kit on a si we bolted it up and we took it for a spin broke it in a little bit. But anyways the first time we got on we felt boost. Now we feel no boost It sounds like the turbo is trying to spool but then it never makes boost we dont have a boost gage yet. Idle is fine and there doesn't appear to be any vacuum leaks. Right now this car is damned slow.
Any ideas?

 

Sounds like there might be a leak somewhere in the plubming. Make sure all the silicone connectors are working properly. Then check the waste gate, make sure thats working properly. check the BOV, etc

 

Yea, check the pipes, esp around the intercooler. this was the problem with my friends car when it boosted the first time out, and then stopped. check the wg too and make sure the BOV isnt leaking

 

im willing to bet its an intercooler pipe.
those come off all the time

 

id go ahead and get a boost guage before things get ugly

 

also check the check valves.

 

I had the same problem with mine and the only thing that was wrong with it was the piping blew apart....But you need to get a boost gauge and a air/fuel soon

 

i had the same problem the first night i took my car out with the kit on it was the conection from the throtalbody to tre intercooler pipe was off check all your pluming

 

does it threw any code ? if it's the missing link, it'll threw a code..

check your all your lines and connectors
