i tried everything thats possible and still cant find out whats going on with the car. the car on idle is perfect once i rev pass 2000 rpm starts misfiring acting like a subaru. also while drive the car has fuel cut pass 2000 rpm. NEED HELP!!!!

your wastegate might be opening and closing back and forth really bad, mine sounded like a subie because of that problem

When you put everything back, did you do a leak test and try to pressurize the entire system to near target boost level before you crank it up the first time?

Is the maf harness plugged in? Assuming its a maf car...

Also check your Crank Angle sensor. It may be on backward.

I would venture to say that timing is off and/or a cylinder has no compression or isn't firing. In my experiences, the car won't run if the crank angle sensor is on backwards.

timing is right on the money and i also checked compression 150 across..

check the plugs. make sure they didnt foul.

were break in procedures done?

if you have exhaust leaking out of the dump tube it could be the wrong gasket. or gasket is blown

when its makes the "subie sound does it sound like its coming from up front? or out the back?

you may need to tighten the preload to make sure the flapper is shut.

also a way to test your wastegate pressure is to by bass you boost controller. take some vacuum line and run it from your j pipe directly to your WGA and see what your boosting that will tell what you WGA is holding preassure wise
