Default Boost fluctations! (mod to move to a better section?)

This whole post has been re worked based on new info.

Still diagnosing boosting issues!

mods:
*EGR delete with race pipe/block off plate is the only mods, and the vacuum ball was removed. (and former vendor alh toyota swapper) did this work. It worked well.
*I did a karma tune, The n239 is tuned out, as is the n18 (i believe have not tested yet) no stored codes in vcds free version.

On to the processes

First i unplugged MAF cured limp mode,
so cleaned the maf which cured limp mode when plunged in
VCDS MAF readings were still low so per some suggestions elsewhere I replaced it.
Well the maf is working well now but the boost is still off, so it did not fix the issue.
I need to know how badly these boost numbers are breaking the turbo/engine.

Boost is still off in VCDS. What does the community thinK?

NEXT
after another nearly sleepless night of better understanding with lots of sifting and learning I tracked down somethings wrong mechanically....
I believe actuator is not working well, OR IS IT THE INTERNAL VEINS STICKING? I can't afford to throw money at this problem!
d.
see video below to see what I believe is causing the derivations between the requested and actual boost.
I don't wanna just pull the turbo, I can't just but an actuator and have it be the turbo vein lever or internals.
I guess the oven cleaner trick is my next bet?

This is clearly why the boost numbers don't match!

****Again how bad are the boost numbers (VCDS PICS above) for the turbo another components? ****

I lubed the actuator arm and moved it around. it still is loud and seems to be binding on something. I have not had a chance to drive since then.

thank you
Dennis

You can drop the log in a Malone window and post the link here. Easier to see.

Looks like one of three things.
Vacuum leak, n75 valve, or needs actuator adjustment.
When was the n75 changed last.
I would replace vacuum lines if the fibers crumble when touched, or the ends re cracking.
N75 seems expensive, however, a spare is nice if it's good.
Actuators wear and stop moving as well as they should.
Adjustment is kinda annoying, but, this doesn't have to be done often.

Remember to log 1500 to at least 4000 if not redline.
Drop the log in Malone website and post link.
This will help a lot!

I'm on the road now, so I'll get back, but did you watch the video of the actuator too?
As soon as I get a chance (probably Wednesday of next week ) I'm gonna take the actuator off and test it that way. The hoses are all testing good when I plug one end and apply vaccume with my toung.

I think the n75 is hard to test! Lol

Thanks for the reply

Today, I hooked up VCDS and monitored 11 boost.
at idle request is 966 actual is 1009 ( something like this) its over boosting. So I went and pulled up on the lever that moves the veins attached to the actuator. Boost then leveled out! So sucked on the hose that connects to the actuator as to actuate it and back to over boosting. SO the actuator is either not able to push the vein lever back into place, OR the veins are stuck? Not so fast!

Next, I Re routed the hoses to eliminate the n18.

Boost (on my gauge) spikes to 18-20 and settles at 12 or 13. However the VCDS still reports slight over boost at idle. but 1500-4500 WOT 3rd gear runs show the boost is actually closer than it was before, in fact a few times it was SPOT on! Weird!


Before, on WOT tests it was spiking to 13 or 14 and settling in at 9 or 10 on the ugage and was slightly off and under boosting

Guess the N18 was bad? Im gonna replace the three hoses now and then see what happens. IF nothing, ill switch the n18 with the n75 and see what happens.

If nothing changes IE boost does not level out to normal than Ill probably get stupid and try a can of oven cleaner? IF no go ill adjust the actuator arm. Then and only then will I remove the turbo and clean it and replace the actuator. First ill check for shaft play onthe turbo tho. Which I need to do any way.


I need to keep searching and reading. THe more I read the same **** over and over (in different threads) the more ideas I get.

I wish this was in the right section and I was getting some other ideas here other than my own! sometimes my ideas suck!

Up to 150 over is good. Actuator seems adjused well. N75 or actuator if it doesn't move easily.

Well in constantly under boost! No good! I'm not sure about this "moves easily" mine seems to make a creaking noise st the end. Pretty sure it's gonna get replaced. They a safe part to get used local guy has one that is basically new so he says and it looks good too
