Message Yes, it was building positive boost and it sounded like it was all rushing out the intercooler. It was my guess it was the intercooler itself or piping right at it the first time I accelerated because where I could hear the sound coming from and I knew the car had previously been wrecked at that corner.

When I drove this car home, the factory boost gauge was showing the turbos were building plenty positive boost and the response seemed excellent compared to my last car. Now I mean as far as watching the gauge when I would roll on the gas, the car wouldn't go anywhere. The noise coming from the front of the car sounded like you put an open tip hose fitting in the end of an air hose when the car started to build boost.

After I put the new intercooler on and fixed all the other leaks I could and I started the engine, noticing the motor was running terrible. It will now build no positive boost and the factory gauge shows its all the way in the vacuum and it will not come off being pegged in the vacuum. When I said the turbos are not spooling I meant they are not moving, wont build any positive boost or even come off -14 vacuum.

But I don't want to make it seem as if i've unhooked the gauge by accident, because it is obvious the turbos are not turning at all. They make no noise at all when the engine is revved.
