So what are my options on fixing this issue i dont wanna blow my **** up mang.

 

^ You have two options, put your stock O2 housing back on or port out the wastegate dump tube side of your aftermarket O2 housing.

 

After market o2 housing+ cold weather=boost creep
Happened to me last winter, even with my boost controller bypassed, i was seeing 19-21 of wg pressure...

 

are you talking about porting out the part of the o2housing that sits on the gasket? i don't really know what Dump tube your talking about. My aftermarket o2 housing is already ported out inside, its one of the ebay one's that i had cleaned up and stuff.


BTW my mod list is below so if that helps any.

 

resurrecting this thread because I just ran into this issue and made my car un-tuneable. I am creeping from 16psi wastegate pressure up to like 24-25 right now.

Is it even worth trying to port out the wastegate side of the o2 housing for that much creep or should I just say F it and put the stocker back on...

I don't think that housing's gains are worth the trouble.

 

same, my ebayo2 had boost creep even though the build quality seemed fine internally. it would hit low 20's quick hit high 20's. (let off quick).

for now my wastegate is adjusted but yes it did increase slight boost lag, sucks kinda.

 

How did you adjust the wastegate? Did you give it less preload? I'm looking for a decent solution here that wouldn't take away a lot of power. Did adjusting your actuator get rid of the creep or just make it less severe?

 

For the people who are getting boost creep, are you also getting knock? If the car isn't knocking then more boost towards redline is a good thing.

 

best way is to remove the wastegate from the manifold (easy to do once you remove the fan). then turn the turnbuckle arm (i believe counterclock-wise) to length it. i would make half turn increments and test as you are in essence creating slight lag (letting boost out) to fight the creep. if i remember correctly one 360 turn did it for me. you will see maybe 500rpm more lag top end will be better then stock o2.

honestly i may simply go back to stock o2, i care less about hp but more powerful midrange.

 

man, now I'm so torn. I might give this a shot to see if it cures my creep without too much loss in spool, but I think the long term solution might be to put that stocker on there for now

 

well dude this is what i would do.... if u dont wanna or cant afford a replacement this solution is a good bandage. if you do minor adjustment it wont make any big change to your power curve. what will be kinda nice is to complete reduction of boost taper... well maybe im exaggerating but you will be hard pressed to see a boost taper now.

 

I think I'm going to try and give it an adjustment until I can put the stock o2 housing back on there later this week or next. I would port out the housing and the hotside near the wastegate but with this much creep I don't think it would solve the issue completely....maybe I just need a bigger turbo and an EWG...
