Have a Nice Day? Reccomended boost level

I have a Japanese 2.0 EJ(Not sure :P) WRX motor with a modified LS intake manifold and a Jap turbo (think its a vf22 which ever is the twin scroll one). I am currently running 10 lbs of boost. The car is tuned and has open port tuning and the shop said I could turn it up to 14 lbs and still be safe. The shop said yes but I just wanted a outside opinion!

And you aren't fluent in cars in general, so don't mess with it before you blow something up as from what you've said so far, your postings appears to be third party translations of English from Portuguese by a non-native speaker of Pig-Latin Portugeuse reading a Braille transcript.

If it helps I have a usdm 02 wrx with the stock ej205 and the stock td04 and most of us push the psi to 20ish but nothing more because it runs out of breath and becomes very inefficient.

Im 90% sure its a JDM EJ205 with the VF22 Twin scroll turbo. Its been tuned and dynoed but its set for a safe 10lbs of boost. The speed shop said I could turn it to 14 and still be safe. I just wanted to confirm this. Cant make it much clearer :P

I have never run a wrx that low so I would think 14 psi is safe.

If a shop "tuned" it and u want more, why o why are u asking a bunch of strangers for more power??? Go back to the shop and ask them to push your setup til it knocks and dial back to a safe tune

I just want an outside opinion from Subaru people. Yes it was also tuned on a awd dyno. I didn't know if 10psi was stock or it was set by the previous owner.

If u want more... You need to talk to the tuner. I'd hate to know that its running so rich u can turn the boost up another 4psi and still be safe.

you're 100% wrong in thinking there is a vf22 twinscroll.

The vf35/6/7 is good for near 20psi, but falls off hard on the compressor map after that.

The vf35 is not a twin scroll to my knowledge.

The vf36/37 still makes great power over 20 psi, I have pushed 23-24 psi and the car pulls really well. it is just hard to hold boost at high RPM since most wastegate actuators are not strong enough to stay closed.

You have the compressor maps for the 36 and 37? I would love to see them.
