Okay I’ve had my k5 gt and I keep having an issue of losing boost at high rpm’s and I don’t mean when I shift. It loses all boost and has to rebuild boost. I’ve noticed it when I’m going 60 then it stops rebuilds boost at 80 mostly and have noticed it when I’m going 100 then rebuilds at like 110.
Told the dealer they said they looked but when I told them they said they couldn’t test it but then said they did so I think they bsed me.
Any ideas?

You might want to look through this thread (it's just below yours as of this post).

Double check that the hoses for your intake and exhaust are clamped on and properly tightened.

See I have boost when I first accelerate. But then it’ll just lose all boost at like 60mph and not gain any back until 80mph
