I am just posting this now because another person I know is having this issue. After installing all block off's after 4,000rpm there is 0psi. Boost from 3,000rpm is 10psi but then when it comes to the transition point no boost at all.

Is there a setting in Power FC that should be used to correct for block off's or this is only a mechanical issue. Hoses are brand new Viton w/ simplification as per www.fd3s.net.

 

thread title says blow-offs (which won't affect a speed density car) but post says block-offs...

mechanical problem though

 

I saw it after wish I could change the title.

Boost pattern was perfect before block off plates.

 

Please list all block-off plates you installed, and we will go from there.
But truefully at this time, I believe you hosed something in the process.
First check you map sesnor hose and TPS connector.

 

I will check everything and report check.

Double throttle eliminated, AWS, EGR, from memory. Hmm what is the one that is on the backside of the engine passenger side?

 

Did you put both on the underside on the upper intake manifold dealing with the aws? One faces the firewall and one faces toward the paseenger side.

ISC which was near the double trottle control.

Maybe you messed up part of the turbo control system as you loose boost around the switch over point.

 

I'm not saying I didn't mess anything up in the process. I will check out all the things you guys mentioned. Thank you for the recommendations, I will report back.

 

yeah sounds like something in the rats nest, rather then a PFC setting. You do have the sequential turbo setting on. correct? Did the car run correctly after the vacuum simplification or were all these things done at once?

 

The car was not running when I got it.

 

then you may need to go back and check the vacuum hoses for the turbo control. or go non sequential and get rid of the rest of the hoses

 

More likely the ACV pipe IMO.
