sts wont boost
Sorry to here im going through the same crap. I only made 2# barely. I have heard putting hair spray in all the silicone couplings, once they dry they seal up pretty good. Im giving it a couple of more trys then the nitrous is going back on.
too bad billy(trt) is in florida...i think he could give some good insite on this issue since he has installed these kits on alot of f bodys with and without headers-wraped and unwraped...he'll be back sunday...maybe he will chime in....

I would wonder why they took it apart. If its not seized, why would they take it apart?
To see how it works? To see if it had an internal air leak? OK, now I'm just being a smart ***, sorry....

you could have a bad coupler and you wont be able to tell while its on the car and sometimes even checking it theroughly because say if you ARE making boost and the air reaches that coupler, it will then expand, letting the air out and the boost not reaching your intake manifold. In most cases this happens on the coupler going into the intercooler and comming out.....what types of clamps are you using to fasten them?? please tell me they are T-bolt clamps and not the shitty hose clamps cause once you boost with hose clamps they loosen up and the coupler blows off the piping. As far as the wastegate goes....you HAFTO hook up a vac. source. If you dont (it still wouldnt prevent you from getting boost) the wastegate will NEVER open and that means BOOM on motor. The wastegate is controlled by the vac. line going into it and the LB spring thats in there. If the wastegate never opens, you will see never ending boost untill your motor blows up. So before you even try to find the boost leak, fix this up incase they do get it to work and then she will blow up. Check your BOV too. The valve could be stuck somewhat open also creating a boost leak. I doubt its a exhaust leak because you should still get something for a spool....good luck

ask them to pressure test it.
pcv pipe with a cap on the end. screw in a air compressor fitting.
connect that to one end of the system back by the turbo.
fill with 10psi of air, listen for leaks.
simple as that to see if anything is leaking.

well before i took it to get tuned, i started it up with the kit on and no tune and revved it up pretty good to see if i could hear the turbo at least spin, but i never did hear anything. i have seen vids of people rev up their sts, and you ususally can hear the turbo at least spin, but it didnt happen that way with me..... i just figured it was all tuning?
and i guess they took it apart to check it out? i dont know, but they told me there is nothing else they can do, and thats when i asked what have they done already to check it..
and yes, tbolt clamps all the way!

well they said they checked the intake side and the exhaust side... i dont know how exactly, but hopefully they did what you said.
Wish I could help more. I know Rick an Synergy can figure it out.
There are not issues with the STS making boost. There is an issue, and more than likely a small one that is keeping it from boosting.
Johnny, I will make this offer. If you want to pay for air fare, I'll send a guy to California to look at it for you.
