Car only going to 8 lbs of boost what could it be ?

[mikegt2]

Have 2022 kia stinger gt2 running jb4 with back end flash was running fine today did wot then next time tried wot only went to 8 lbs of boost first thing did was check afe charge pipes didn't see anything loose but hard to tell just laying under the car, then tried my lap 3 tune did same thing so should count out the tune, anyone have idea what it could be ? Runs fine up to 8lbs of boost. Included data log you can see part of it ecu boost shows 0 and boost shows over 20 and pedal is only at 10-11 so something is going on and after that has not went over 8 lbs of boost.

Look at line 94 and ecu boost is at 0 and jb4 boost showing over 20 with pedal between 10-12.

First thing that comes to mind is a boost leak. I've not had to track one of those on a Stinger before, though. Has anyone been in the engine bay recently?

Yes had charge pipes installed last week, would say that's where boost leak is visually checked them and tried move the pips seemed tight but taken to shop this week have check for leak.

I would have them check their work.
