Hey fellas I'm back, but I have a problem! When I'm driving down the road, I'm getting a real hard sucking air sound from the intake side! I'm running now psi on boost, but the turbo sounds like it is really spooling! All boots seem to be intact, although there is one that I am kind of worried about!

If you have a boot off you would'nt build boost,You sure you not hearing the intake through the BHAF(or have you had that on for awhile)

I've been running bhaf for a while, but I can really hear the turbo spooling last couple of days! an it's puffing out black smoke like you wouldn't believe! I was pulling my 45' tandem dual gooseneck with a lil 4 door car on it the other night, my brother was beside me in my other dually an I poured the coal too it an he said you couldn't see the tail lights on the trailer, the smoke was so thick!

Check the first boot coming off the turbo. I had that one loosen a couple of times and it had one hell of a hiss and smoked a lot too.
