Update!

i played a little bit with the MBC and turned up the boost, the boost started to spike up then down, fluctuation so i stopped immediately. and then i found out that the stock boost control solenoid is still in place, so i disconnected the hoses from the MBC and and connected them to the stock solenoid. it became stable but only 14PSI. btw i idle at -9.9 PSI.

Do you think i have a boost leak or something wrong with the turbo or the wastegate?

and on another topic, i want to recirculate my HKS SSQV4 BOV. and im missing the nipple that can be fitted on the head of the BOV to connect it back to the intake, can i buy this separately? can you provide a link?

Thanks.

 

First thing id do is figure out how in the world you're idling at 9psi. I don't even think that's mechanically possible...

I'd peek back under the hood and make sure that the hoses are hooked up correctly and then double check your boost gauge installation - sounds to me like a faulty gauge or problem install.

im very sorry i meant -9.9 PSI
i'll edit it now

 

update 2!

Today i went to a shop "supposedly specializes in Evos" and i did a boost leak test and there were non. He removed the cone filter and started pressurising from there.
He also said that 14 PSI is the stock boost smh.
Anyway, on my way home i did a WOT and just after it the service engine soon light came on, and guess what, p0171, too lean. Guys im freaking out now,can anyone help?
I did some research and the people sayin that the ams CAI can cause the SES light and its no big deal.
Ps. The tune in the car is cobb v403 stage 1 +sf 91oct. And on high rpms the boost is about 12.5-13.5. if i posted a log can someone help.

Thanks.

 

lol I love the modest thread title.

 

I'd do an internet tune personally. Grab a vendor off of here that specializes in them. You're playing with fire without knowing about the current tune and what it was tuned for. If it was tuned for that MBC and you took that off, all sorts of bad things can happen if you hit boost.

Do yourself a favor, remove that MBC, get a 3-port and a tune and be done with it. That check engine light is telling you that you need to do this.

 

i already removed the MBC and connected the stock solenoid and put a tune from Cobb "of the shelf"

 

A tune from Cobb off shelf isn't taking into account your specific parts and set up. If you're throwing codes that tune is probably not right for your set up.

 

That's true i will get an etune, but my main issue is that there's​ no proper boost.
Btw the code went away today by it self.

 

You said you just had a boost leak test done and there were none, your issue is most likely your tune...just due what everyone is already telling you and grab someone off hear and pay for an etune before you blow up your car.
