well i pulled the wastegate line and just left it open to the atmosphere
, when thru a 1st and 2nd gear run and still got only 7psi,
then i went and pluged the line with a vacuum block(the wastegate actuator) and i
when for a nother run thru 1st and 2nd and in 2nd
i got about 9 or 10psi.
also this is on a internal wastegate.
thanks

well somethings not right, cause you can only raise the boost with a MBC, not lower it.

i meant that I could lower from 7psi to 5 psi, the stock wastegate is off a saab t3 and i
think the stock saab gate is set a 5 psi.

think my problem might me my wastegate, cause in both set-ups i had to mount the gate with a bracket,and not to the comp housing like it is stock, with the new .60/.63 t3 i had to mount the gate further away form it's old mounting point and it moves a little when it starts opening, im going to add a nother brace to it and see if that helps.
or im going to try a diffrent wastegate.
thanks

well if you pulled the vac line it would stay closed the entire time regardless. You most likely have it mounted in a way that leaves it open to some degree or you just have a bad boost gauge.

well let me explain this whole moving thing better for you guys.
when the gate is fully closed(no psi) it doesn't move at all it secured nicely.
now when you ably pressure to the wastegate via the vaccum hose,when i reaches 4 or 5 psi(stock wastegate setting), the wastegate rod will start to move like it's sopose to, but there is to much force for my braket and it will pull the gate back about a 1/4 inch.

here is a example........ my wastwegate rod moves left to open the flapper door, so the rod starts to move left and there is enough force there to move the acutaor to the right about a 1/4 inch, then once pressure is gone the rod moves back and the mount moves back and it is fully closed,meaning the flapper door is complete closed also i had check to make sure it was fully closing the flapper door.
it's kinda hard to explain,maybe this will help some more.

could this be true, max psi can change/be lower in certain gears??
i would thry this but, i sprung a leak in my rad. so i cant try it out untill i get a new rad.
thanks
