96 gst Turbo sputtering or something lol

Hi guys was wondering if anyone has come across this, car will run and drive fine until I get on it then it will start to sputter until I shift dropping boost down.

I have done spark plugs gapped and everything got new ngk spark plugs and new stock bov. IDK why it keeps giving me trouble, no play at all in turbo no up down or in or out.

Kind of at a loss here

I would run a boost leak test just to rule that out as a factor

Check the spark plug wires too. If you can get into boost at all but not full throttle. I've seen hard misfires through the boot. Shows up as a small white dot. If you bog down right at boost onset a boost leak is more likely. Both should be checked honestly.

Is this a new problem? It's possible you're running out fuel pump too. Need to know the history of the issue.

It's a new thing was running fine like a month ago took it I to get trans mounts and engine mounts done when I got it back it started cars stock no real mods just cold air intake the spark plugs, wires and bov 133k on it did some other things to it like change out slave and master clutch cylinder tran went out so it has a lower mileage stock one with new clutch and that's about all I have done to it

Did it do this exactly when you got it back or is this some time later?
