i just recently riged up a custom turbo kit for my 90 lude. its a log stlye manifold with a ss Autochrome wastegate and a new Airesearch turbochager. when i put it all together with my old manifold that was made of mild steel and kept cracking it ran fine until one day it just stop boosting. When it stopped it start making some weird loud noise everytime i pressed the gas. a noise like i no there is some sort of boost leak but the leak and the noise is from around the manifold turbo area. welll i changed the manifold for a stainless steel think that was leaking but the same outcome. then thinking it was my wastegate i blocked it off. still the same. the last thing i figured it could be was the turbo. why??? b/c my turbo has a wable in it due to my car backfired one time. is it the turbo thats making by car not boost or anthing else. all the pipes are tight and there is no leakage from the mani anywhere.

help please. if i cant fix it im gonna be forced to sell.
