OMGHi2U I hope this is the right fix...

I was under the assumption for about a week since my AP has flashed my car to stage 2 that I was indeed stage 2. Today, with the help of a friend (thanks Joe) I found out that I am boosting under WOT about 10.2 steady PSI. I hear about 15.7 is about the norm for a stage 2 WRX.

We plugged in the AP to read boost levels and that's how I came to the 10.2 - Just and FYI.

Some of the things we did to try to assess the situation, not in any particular order (Joe please chime in if I leave anything out):

-Reset my negative on the battery terminal
-Installed a working boost control solenoid
-Installed some different wastegate lines (not new or anything)
-Made sure the correct map was loaded onto the car in the first place
-Checked to make sure the two green test connectors weren't connected
-Made sure the Pil was in the correct hose and in the correct spot in front of the turbo to the right of the T
-Joe please fill in anything I might have missed...

We also took all of my boost lines off to check to see IF my car could even boost over 10.2PSI. Which it did, knowing what to do and what not to do with this we saw it shoot up no problem to 17.4PSI, after which we put the boost lines back together as to not blow my turbo...

The idea here is tomorrow I will order a brand new wastegate line assembly (just hoses) to rule that out, obviously there is something wrong with these...

Just wanted to see if anyone else had any further advice/insight? I searched this thing but have tried almost everything to try..thanks.

-Danny

Well I called up COBB just to see what they thought about the whole situation and the guy said that you need to put a load on the car. Meaning I should go out to the local highway, going the regular speed (3rd gear) then just jump up to 5th gear and punch it. This sounds good on paper but didn't work (unless you give yourself miles of space) so I put it back in 3rd, maxed out 3rd and hit 4th, almost maxed it out @ 100mph just to see what I'd read on the AP, it said 12.5PSI. I think the problem lays in my lines. When we disconnected them it was running fine so it has to be those, I will just spend the $40 at the dealership to buy all new waste gate rubber hoses. Should fix the problem.

I'd tighten your WG arm also. You may have a nice loose WG.

ok so we tightened the WG arm (almost fully) and I hit 12 PSI. This is still below factory boost but I guess it's a start. We tightened it up just about all the way (1 1/2 turns more) and at WOT up to 4th gear I was only holding roughly 10.6PSI. How confusing this is...any suggestions nasioc?

My friends and I put on the Ebay TMIC and the car still couldn't hit target boost. I am going to purchase the necessary items to make my own boost leak tester.

UPDATE:

Took off the headers heatshield and noticed a bolt was missing, filled the gap. Test drove it, still not hitting target boost.

Installed the new gasket, as I expected from looking at the old one, still didn't fix the problem. I hit about 12.4PSI at WOT

I guess the only thing left for me is to make this boost leak tester, this has been a real PITA..

Thanks

OK so I'm really frustrated I tapped off the boost gauge line in my car to see if that could be the problem and it wasn't how retarded? I have no real clue what it could be..could the cam timing be off or something? does anyone have any ideas? Read up and check, I've tried almost everything I think...ANY suggestions except driving the car off a cliff will be considered.

Also, I tightened the actuator arm ALL the way and I peaked at 12.4 it was actually lower then this when the arm was more loose. Yeah, bad stuff, if ANYONE has ANY ideas, please let me know.
