Well I found out that was not the problem we ran into a few things and fixed them and now everything is working properly but now there is a new problem it wants to cut at 5000 rpms only when you lay on the petal also getting a humming noise. Any ideas guys that could help me I know there has to be a vac leak bc I just hooked a gauge and from everything I've read what were getting is not right but what I'm wondering is would that make the car cut like that when you just drive it has no problems meaning no noise and no cut

It's your vacuum leak that's your problem. Find that, and it will be fixed. Could be a broken wastegate actuator.

Vacuum leak, ignition coils, failing WGA
