more like a faulty solenoid. Got a few q\'s to try and help fella.
When it drops off boost at what revs does it do this?
Are u still sequential?
Can you hear any boost escaping, if not disconnect the Charge relief valve (looks like a dump valve ish and is at the back of the engine bay next to the y-pipe) and when you do can you hear any boost escaping then?
Can you describe the boost patern when this loss of boost occurs?
Hopefully we\'ll get it for ya bud!
