Don't answer.

 

What?

I was thinking of something different (more vacuum related) when I made the thread months ago and had no experience with these motors so didn't know how the vacuum lines should be routed. Now the motor, trans, and tc is out ha but I found someone hooked the inlet of the fuel pressure solenoid up but left the outlet hooked to nothing, and regular vacuum was going straight to the fp regulator, the vac/boost gauge was tee'd into that vacuum source so the gauge was reading 7in since the solenoid was open and making a constant leak but yet I checked at another intake port and it was at 17in of vacuum, the leak was so small that it wasn't enough to affect the overall vacuum too much. You would think the person that tuned it would have figured there was a problem But basically, if the engine was getting 35psi the boost gauge was reading less because once it got to the source line for the boost gauge the boost was pissing out of the solenoid so the boost gauge was reading less than what it really was.

 

Now that wasn't hard was it?

 

At the time I didn't own the car and didn't know **** about evo's so I didn't know what I was looking at, if it was done right or wrong and couldn't be ripping stuff apart on a stranger's car...so I couldn't fully explain the situation but I knew the boost gauge was reading different than the actual boost/vacuum

 

I had the exact same problem with my evo the car would only top off at 12psi and it would hold.. But me and my friend discovered that the vacuum
Lines were placed backwards!!! After we fixed it it went to stock 19psi YEAH!!!!! ^_^

 

Saweet, how was the lines backwards? Which line was it?

 

On my evo it was the vacuum lines from the solenoid to the wastegate! I'm sorry I don't have a diagram but you'll have to remove your air intake to get to the solenoid.. There's a black and red cable and it's possible that You just need to switch them! =D

Let me know how it goes!!!

 

That's why computers are great. If u wanna know just log the MAP sensor data. Unless the sensor is broken that will tell u how much psi is building in the intake manifold.

 

Assuming you're talking about the boost solenoid, I don't have one, I just have a manual (forge) boost controller, someday going to get an electronic and I don't have the stock intake system anyway, I dont even know what a stock intake setup looks like

 

I'm talking about to your wastegate are your vacuum lines all in the same place as they should be?? Cuz one of the
Has a pill in it and maybe the pill is plugging up the same whole.. There should be a red and black wire.. Try to look up a diagram for it =D

 

Pretty sure your talking about the stock setup....I had a thread showing my lines but cant find the thread. Basically went from turbo to bov and to intake, thats it, as far as wastegate lines go anyway, no pills, solenoids, etc...

The only solenoid i have in any line is a boost solenoid for the failsafe for my meth kit. The turbo is controlled from a manual boost controller, aftermarket turbo and actuator so I dont think the pill would even work good with that stuff and with 30+ boost
