·Background info: Car has 52k miles, has been BPU for 3k miles. I was getting onto a freeway on ramp and gunned the car so I could merge with the traffic. The second turbo kicked in at 1 BAR. Around 6k rpm, I heard a hissing sound, more like something leaking then a BOV sound. Then the boost dropped to .6 BAR.
On the way home, I noticed the first turbo would not boost over .4 BAR. Car barely rev past 3k rpm. If I try to push it past that point the car stutters (felt like a fuel cut) and black smoke would come out from the exhaust.
The car still holds perfect idle and vacuum. I heard no death whine. My immediate conclusion was that an IC hose must have popped off.
I checked the IC hose. They were all tightened. I couldn't get to the one below the intake so I figure I would have Toyota check it out for me.
I got a call from Toyota and they said they couldn't find anything. The service manager suggested my 1st turbo might be bad, but he will need to keep the car to run further diagnostics.
My question is, if my first turbo is bad, wouldn't I hear the infamous death whine? Also, I have always thought black smoke coming out from the exhaust is correlated with popped IC hose? Or am I mistaken?
