were is the wastegate line ran to? could it have a vac leak for that or not be hooked up right? or maybe you are boosting but its just your gauge? how high did you get your rpms?
oh also were you driving while reving it or just sitting there. i cant get into boost or atleast cant see it on the gauge sitting still gotta have a load on it.
it also could verry well be just your heat sheild is blocking the arm from movimg properly

all good points, the wastegate line is routed to the port on the compressor, the bov is plumb there as well, but I think its fine and hadnt blown off.
the gauge is a little sunpro pos but I certainly didnt feel any boost from idle to redline, uphill (up university->park->washington, we live near each other), or wot. the gauge is plumb inline with the autotune pressure switch, is it possible the pressure switch is backwards? just thought of that, I dont remember any markings on it but...
and I was going to check the heat shield but it was hot and I had to run a part back to the shop right away... thats on the list of suspects tonight. it also could be the cotter pin on the wastegate arm, maybe it broke?

The bracket holding the actuator to the housing looks bent. The circled part of the picture can't look like that naturally. Either during shipping or by mishandling, the actuator bracket has been bent and has actually moved the can closer to the CHRA and is holding the flapper open.
With a pair of pliers, grab the bracket and bent it back straight until the rod starts to be pulled out of the can when the flapper is fully closed.
ANYBODY ELSE WANT TO BACK ME UP ON THIS, OR AM I CRAZY?

ok well I got home at took a look at everything...
A. it was being held open, the bracket is bent because the guy tried that before modding the wastegate arm...
B. I spaced the wastegate so that it was closed
C. wastegate blew up when I pressure tested it.
conclusion need new wastegate YAY!
anyone have a 16g wastegate for sale cheap?

This doesn't sound like anything zip-ties can fix
