last night and most recently i took the car to a local "track" and had some issues. when accelerating the car spits or bogs or something where it makes the car jerk above 14psi. it sounds like the turbo is sneezing out of the bov violently. it does this jerking sneezing hokey pokey motion until the rpms hits about 4500-5000 and the boost drops down to 11 psi. it does this not only on the track but local driving as well.
i have no codes and no check engine light on so its not electrical, i just changed the plugs about 2 months ago and i checked them periodically and they aren't burnt broken or damaged. I installed a screamin demon ignition about 1 1/2 years ago along with 10 mm wires. so its not that. it has the srt stage 1 upgrade with the bigger injectors so im getting plenty of fuel. all turbo vacuum lines have been checked and inspected nothing cracked or missing, that goes along with the charge pipes those are fine too.
i think the waste gate isnt working because the fluttering of the turbo and/or wg is no longer there. im losing alot of power and its getting worse day by day even passing traffic is dangerous because of the lack of power.
any idea guys please help

Yes sir. I have a 2003 Dream Cruiser Auto stick. I kno exactly what you are talking about. Just solved a very similar problem.
Where are your plugs gapped at ? I had exactly the same symptoms u are describing. No codes, new plugs and wires, no boost or vaccume leaks, nothing.
I couldnt for the life of me, figure out why my car would get this bog or hesitate between 4500 and 5500 rpms at wide open throttle.
Wanna know what it was ? I gapped the plugs at .035 before I put AMX hard pipes on the car. After I changed the pipes, the boost went up by 1 to 2 lbs, and then started getting this miss. I took the plugs out, and lowered the gap to .030. Problem cured.
Try it, see what happens. By the way, what number is ur dream cruiser ?
