installed boost controller and now i have boost creep???

[dsm92talonboost]

so i installed a boost controller today and when i boost it sits on around 11 psi for about three seconds and than creeps up to 20..... dont like that what can cause this?

 

[DSMxJB]

What kind of boost controller? How did you install it?

 

[dsm92talonboost]

boughht this one i know its ebay but i know ppl who have ran this and never had a problem. 1-30 PSI IN-CABIN MANUAL TURBO BOOST CONTROLLER PURPLE | eBay
but i ran it just how it said one going to the wastegate one going to the compressor housing.

 

[DSMxJB]

Well if it's installed right Idk. Sounds like it's installed like mine. Maybe a faulty product? Or may have something to do with the in cabin part, I don't have in cabin and have no issues.

 

[dsm92talonboost]

well i dont have it in the cabin either i have it right by my rad fan.

 

[DSMxJB]

Well, if you installed it like this Idk what is wrong. Sorry I can't be any more help.

 

[dsm92talonboost]

yep thats how its installed. i was also told that you may have to port the wastegate flapper?

 

[DSMxJB]

I'm not sure. I never ported mine and I can adjust boost just fine. I use this one from ebay and I have had good results with it so far. It has some minor surface rust after about a year but I can't complain for the price. NXS MANUAL BOOST CONTROLLER DSM GSX GST TSI ECLIPSE VR4 | eBay

It's a cheap bleeder style valve. It will creep. To fix it buy a better quality one I suppose.


Mine did the same thing. I found a TurboXS one on the classifieds here for $20 and it works great.

I just got done with my evo 3 swap and now im having boost creep... im running a Hallman mbc so im sure it's not the boost controller and there hooked up the right way... any advice?

 

[my dreamt dsm]

16g are notorious for creep. Thats why you port.

 

[miguelmcv]

What down pipe are you guys using.

If you are using a 3", it will creep, unless you do some porting.

 

[99ECLIPSEGSXDSM]

I'm running a rre 2.5 to 3 downpipe. It was ported when I bought the turbo from fp.

could be a restrictive o2 housing

I know it may sound totally off the wall, but, have your checked for quality on your vac lines?
If you have poor, cracked, aged, or loose lines connected you will suffer performance. This is why you read about ppl asking if you have boost leak tested your car so much.
Have you? Tested?
As for that type of mbc, you may want to inspect it inside and make sure spring etc is actually in there. Just curious since a mbc is not rocket science, pretty simple contraption, so if you are suffering creep after inspection of all else, leaks etc, it sounds like something is going on inside it. just my .02c

 

[90_eclipse]

make sure you try to keep the vac lines as short as possible.

im running meggan racing full 3 in turbo back exhaust no cat... i think thats my problem. but yes spring is in their, no boost/vacuum leak. i removed the mbc and im still creepin.

 

[gusu]

Port your turbo. Should fix it.

When I went with a megan 3 in dp I got boost creep just like that but sits at 10psi and spikes to 23 I just tuned for it . Thats an E3 with E3 o2 housing and megan dp catless to thermal catback. Hallman pro mbc. Turbo is ported too.

 

[Funfettie]

Id recommend an o2 dump. I had mad creep with my 68hta, and an o2 dump stopped all creep. there super loud and aggressive under full boost!

 

[rlacasse1]

I would say if you did not have creep before, and you installed a boost controller, a cheap one at that, then it is probably the issue.

Take the boost controller out of the equation, and wait until you get a decent quality boost controller.

 

[99ECLIPSEGSXDSM]

Just tried a Megan 2.5 u2 housing and still does it. I'm gonna try the open dump when I get money to buy one

 

[92AWDHX40]

Got my housing ported, helps running a mhi 18g or 20g yet still deciding.

 

[honda_burner]

i just bought a small 16g and already have a 3" turbo back. should i be expecting this when i get my turbo installed? (just bought a turbo xs mbc to put on with my 16g too)
