Hey all,
I recently had an issue arise on my truck during a little road trip I was on. The issue I am seeing is the turbo will spool up to about 10-12 lbs, then all of a sudden the boost drops off to zero and the truck starts smoking and will not accelerate, as if the veins opened all the way up. The boost will stay at 0 until you let off the throttle and get back into it, and it still will only boost to 10 lbs
During this, all PIDs look normal to me. EBP, VGT, ICP all look normal for an accel situation. The only thing that is incorrect is the boost. I recent took the turbo out and cleaned it (didnt look bad at all) and also tried a different VGT solenoid, Neither of those things changed the problem.
To me it does not seem like a CAC pipe leak since I cannot hear any loud *wooshing* when the boost level drops to zero. I was told by a friend it might have to do with the internal actuator in the turbo that moves the veins (I was under the impression the VGT solenoid was the component that did this)? I'm at the point where I might just buy a used turbo and throw it in. Turbo is an 03 style.
Any input is appreciated.
Thanks
