Boost psi max
What is the max psi I should be reading for a stock turbo with a full turboback exhaust with sf cobb intake?
From my ap stage 2 lwg im getting about 19 to 20 psi.
I was wondering what is max psi I can get without breaking anything.
Perrin catback exhaust
Perrin downpipe
Cobb sf intake
Stage 2 lwg map

I am no expert but 19-20 on a LWG map seems a bit high.
Does it stay there for a long RPM range or is it just a quick 2-300RPM spike?
Does it only happen at WOT?
From your post im not sure if your saying you want a high PSI or are you concerned about it? (Max with out breaking anything?)
You can always do a log and send it to Bill @ Cobb on NASIOC. He usually responds with in a day.
EDIT: didnt realize you are in Hawaii just PM Cobb on NASIOC not sure who Hawaii's rep is.

Well this is one of those questions that is hard to answer but just to compare. My 05wrx on a vf39, 550cc injectors, EBCS, full exhaust runs 19 constantly. Sometimes if I'm cruising in 5th and wot it might go to 20 but drops back down to 19. Been like this for 2 years and haven't broken anything. PDX tuned

since you're new i'll give you the best advice for noobs. at the top of the page there is a search option. use it. there are also search engines like google, yahoo, bing, ect. use them. if you do this you will find answers to 99% of all your questions. if you try this and really just can't find an answer, then and only then should you post it. Otherwise you'll get answers like Brfatal's. tbh we are all sick of answering the same questions so do us a favor and L2Search.

Actually
Let me be of service since you have already been told about the search feature.
Your OTS map from COBB has all the boost, fuel, and timing perameters built into it.
Whatever you are showing for boost is what the OTS map has told it to run.
Is the car capable of more or a more aggressive tune, yes.
You are now talking about a protune.
I hope I have been slightly more insightful.
