03 vgt solenoid question

http://youtu.be/H4f8ZxOjlVg

^Video of my vgt veins and unison ring working fine (atleast it appears to be smooth) i cleaned it a few months ago... My turbo still has compressor surge while shifting and even slightly letting off the go pedal and idles with almost one pound of boost. No p0299 or any other codes its just not operating correctly.. The solenoid does control it ( unplug and it will go down to vaccuum pressure) is this a pcm flash problem? It does it while stock, tow tune and performance tune. Is the solenoid bad, it has a crack in the plug?

Have you performed the turbo vgt relearn procedure? The solenoid looks rough.

Yea the tip of the solenoid is a little gummed up. I changed the oil with some hotshots and the rough idle cleared up. I tried the vgt relearn by clearing pcm cycling key two times letting it idle or 5 minutes then shutting off then driving... Still nothing. I followed the procedure posted on the org, but the vgt did not "cycle" as it said it would while idling. I thought the new pcm flashes cycled the vgt at idle to reduce sticking veins?- is that correct or only when you have a egr installed?

Did i do the procedure wrong? Ive done it before succesfully a year ago after my egr delete( thats when i cracked my up pipes) but this is pissing me off... I pull some heavy loads and i feel like the compressor side is going to explode after i let off the go pedal.

I would suspect your vgt solenoid may be a part of the problem, I would look at the map sensor hose for clogging/deterioration. The problems you describe sound familiar with vgt and/or map sensor. I believe others have replaced the map sensor with success, you just don't see that often. Your turbo appears to operate smoothly. Even with an egr delete your vanes will still sweep with the later strategy, you can find the strategy on the cts in the info section.

Well i run my mechanical in-cab boost gauge off the map sensor hose and it reads the same numbers as the MAP PID... I wish i had AE and could control the vgt to determine if it is following the duty cycle correctly hwell:

I found a leaking cac boot. Got that fixed and now it has some serious compressor surge when easing off the throttle, shifting, etc. can anyone shed some light as to testing the vgt solenoid operation. All the mechanics work but is there a way to test if the solenoid is getting the right duty cycle/ actuating correctly.
Thanks!
