The valve is closed during boost.

The two things it could be or a combination of both. The new filter and new intercooler are a restriction. I bet it's the intercooler. Does the new fmic have the long horizontal "tubes" compared to the short procharger style?

 

If the intercooler was a restriction, wouldn't he see more boost? If it flows better then it would see less boost.
If he ran piping from the Procharger to the throttle body, no intercooler he would see even less boost.
If the intercooler and new intake tube dropped you a few psi in boost then its flowing better. So pulley down, get back up to 12 psi and then you will feel a bigger increase in power.

 

It did feel just as fast. But my intake temps didn't go over 75 and it was about 50 outside and I was running 14* vs 8* of timing but afr was about 8. I've had the nnbs intake on for awhile. The intercooler is a 27x8x4" and flows strait through. I already put the 3.6" pulley on. I was running the 3.85" and I'm getting about 1.5 psi over what I was getting before. I'll do some more testing this weekend.

 

Where is your boost guage referanced?

 

If he reads boost before the intercooler then your right. If he reads boost at the intake manifold then I'm right.

 

I have a vacuum block attached to where the brake booster hose was. That's where the boost gauge is. I also read boost from the map sensor with efi live

 

Good lord that is rich!!!!

 

So you are 2bar?

 

Yes. I'm running a cos with a 2 bar sensor

 

The intake manifold is not seeing as much air(restriction prior to intake) causing lower boost and rich condition. If it was more efficient it would be leaner not richer.
