Mine has been running about 9-10 pounds. Did you actually confirm what springs were in your wastegates? Somebody mentioned awhile back that backpressure could be the cause of the overboost problem.

Verdad Gallardo the spring feels like it has some force behind it its not thin at all so were can i get some small ones at ? thanks for the info and on the box for the wastegates it said it had .5 bar springs in
.5 bar is about 7.5 psi. So they should have the right springs.You go to tial website it shows the different springs. I guess its possible the springs are wrong. Also couple other possiblities might be vacuum leak in the lines somewhere to the gates or connected to the gates. Some guys use zipties to hold the lines onto things securely or very small clamps.
Any chance its your gauge?

Isn't there a way to adjust the spring in the wastegate without changing the springs? I thought someone said you can twist something or spin something to adjust the spring load. That way you can fine tune them. I guess I got lucky and mine were set correctly. I didn't check them and they peak at 7.5-8psi. But I did get a PM to check them after I had my install finished and never got a chance to take them off to look. But when the car got tuned they seemed to be OK so I forgot about it.
They are simply big springs in the gates. Not much in there to play with and no adjustment .I think some guys do put in shims to get more boost but not less.
Usually tial gates are very good ,hopefully they will figure out whats up with the high boost. Not a good thing on a stock bottom engine for sure. I have seen many blown ringlands on stock hypercrap pistons.

air pickup try hooking up the wategate reference line as close as possible to the turbo. i.e. if you have 2-3 psi drop across your IC, then the pressure at the intake will be referenced to the turbo before the intercooler, so you will get less boost at the intake.
im going with springs at this piont thanks that is a good idea but it does not apply here
