LBZ: In Park/Neutral...

newp. its normal. when mine goes into high idle in the winter I have seen it come up to as much as 2 or 3 mph in park.
Well, I think I've got the boost under control. Variation is minimal now 3-5 psi and not noticeable unless you are watching the gauge. It was horrid before and way bad. Now I'm dealing with the huge violent stumble it has. Its like its hydro locked, feels like the engine just literally stops in its tracks for a split second and violently shudders the entire truck, then all is normal until it does it again. It doesn't happen every time, about 75-95%. And never below about 50 mph. Sometimes once, sometimes twice, and has even been three times in a single run.
I cannot figure out this problem. I've tried a few things.
Next will be a fuel filter even though the one(s) on there are fairly new and the idle pressure with lift pumps is about 7.5 psi. I'm about to go stock and give up. I cannot do anything, race, street play, haul my camper and boat at WOT or near WOT. Last time it happed while towing felt like it was going to toss my truck camper out of the bed.
Here is the thread I'm currently working on http://208.109.104.11/forum/showthread.php?t=5795 and posted logs with it happening. No one can figure it out. It does not happen stock.
