My car does that too, I hear that there are some free ways toget alittle more performance out of the stock turbos. Something about tweaking the waistgate? dunno but maybe someone does.

My car is bone stock, I havent done anything to it yet. My boost, for the most part only will hit 7lbs, but yesterday and this morning I saw it hit 12. Why would it not be consistant? When the car is idling the pressure sits at -7, rev it in neutral and itll come up to 0. stomp on it through first, and second, and I'll only hit 7. very annoying. I wonder if its the little vacume solinoid that sits on top of the factory aircleaner. Its connected to the turbo and the waistgate

~ Buy a 2 rubber cap from the Home Depot Plumbing section ($4.99)
~ Buy an Upright Bike Pump
~ Buy a straight fitting (to put 2 silicone hoses together)
~ Buy a T fitting

Cap off the turbo, put a pipe between the turbo and the side wall of the car so the cap doesn't pop off. Cut the bike pump hose and put a long silicone hose on the end of it, and T that hose to your BOV line. Then put a screwdriver in your TB to keep the plate open.
It takes about 25 pumps to reach 15psi. If you pump 25 times and see 0 psi? That means you have a huge boost leak. Usually, at 20psi pressure, your psi should bleed down very slowly, meaning you can run from the engine bay to your boost gauge and still see psi. That's ok...
Check your bov line, check your EGR side vacuum hose
also check the flange or the plastic piece your bov sits on it may be cracked and leaking...

You guys should look into a manual boost controller they are cheap or you could just make your own...that is what i did and i'm running 15psi on it ... also i don't know if you guys have that bcs restrictor like on my 2G it was good for 2psi more... but DON'T DON'T go raising your boost if you do not have a boost guage...you don't want to go blowing your turbo...

1. Move the coolant reservoir out of the way and lay it somewhere in the engine compartment so it doesn't leak. You don't HAVE to do this but it just makes life easier.
2. Use a 10mm socket or open ended wrench to remove the nut holding the WGS to the frame.
3. Remove the electrical connection from the WGS.
4. Remove both hoses from the WGS.
5. Looking at the WGS you can see that the bottom hole is smaller. If you look even closer you can see that there is actually an insert in there which is making the opening smaller. can see that the bottom
6. You can use any number of tools to remove the restrictor: small needle nose, paper clip, wood/sheet metal screw, small screw driver, etc. The important thing is NOT to break it. The mod goes from free to $60 real fast DOH!! I used a sheet metal screw and medium needle nose. I threaded the screw into the hole until the restrictor started to turn. Then I turned and pulled the screw at the same time. This only got it halfway out before the screw slipped out. Then I used the pliers to pull it the rest of the way. This method seemed to work very well and never made me feel like I was about to break the WGS nipple. I even think I could put the restrictor back in, though why would I
7. Re-connect the hoses (hint: the one with the metal clip goes on the bottom
8. Re-connect the electrical connector (you'll only get 8-9 psi if you forget )
9. Re-attach the WGS to the frame
10. Replace the coolant reservoir
11. Close your hood

the restrictor is in the selinoid not the tube, i don't know if 1g's have this same restrictor...i know that my 2g did

 

[xBOOSTx]

if you get yourself a manual boost controller, you wont even need that selinoid...

check if your wastegate flapper might be loose, i had this problem for like a couple of weeks til i found it by messing around! http://members.shaw.ca/dsm.1000q/Engineprimer/wastegate.jpg
