im i suppose to get boost creap even already have mbc.???

 

what turbo?

 

just stock evo8 mr turbo with ported hotside inlet and oulet..... ported stock exhaust manifold.......megan o2 hausing,injen intake kit,.................this thing hit almost 26 psi....whats safe pressure for stock motor anyway....or my mbc just got stock because its too cold today

 

Hey, I had the same problem. It is the Megan o2 housing. The Merge hole is way too small. Take the downpipe off and use an electric drill and demel bit and u can open it up to about the size of a golf ball and u will be good to go.

 

here is the thread where i asked the same question https://www.evolutionm.net/forums/sh...064&highlight=

turn the mbc all the way down until u get it fixed

 

26 psi is fine if you have the supporting mods and are tuned for it.

 

i had the o2 hausing for couple of weeks and was fine till i install the injen intake..............hope its just the mbc got frozen hate to take this thing back out

 

did u have to take 02 hausing out to port the merge hole

 

no I just took the downpipe off and worked on it from underneath the car

 

PORTED THAT MERGE HOLE TODAY ,, THEY LEFT ALOT OF MATERIAL IN THER I PROBLY ENLARGE THAT WHOLE BY 30% ....SO IF YOU GUYS END UP BUYING MEGAN O2 HAUSING MAKE SURE U PORT THE HECK OUT OF THE MERGE WHOLE....BEFORE U PUT IT IN.....OR JUST GET A BETTER HAUSING ALL TOGETHER...MONEY GONE....THATS FOR HELP GUYS GOT RID OF THAT BOOST CREEP

 

Yep, it's usually the wastegate opening on the megans and other generic ebay o2 housings.
