I'm driving right now and when I get the car in any boost it feels like the engine is misfiring. It feels like a flat spot in the power band. I set the car up with a manual boost controller and set it to 12-13psi. Lately it's maxed out at 10psi but I have not adjusted the controller since I last set it. Also my mpgs are trash at around 9-10mpg. I don't currently have an oxygen sensor installed and I know that's contributing to the poor fuel consumption but idk about the intermittent stutter in boost. The engine also has an intermittent high idle after driving a little ways. I swapped out the idle air module(?) the thing below the ecu in the passenger footwell. Didn't seem to make a difference.
Also I have a v16 cam so I know the powerband is higher up but this is all occurring in all rpms
All my windows and sunroof are fully open and I'm on the freeway but I don't think the wind resistance would cause that
So I'm at a loss. Mystery boost leak?
Info about car
Stock k jet
15g turbo

Thanks for your advice
edit: i just checked the spark plugs and they were tight, but the tip (part that screws on/off and what the boot makes contact with) was loose so maybe it had some bad spark because of bad contact? They weren't about to fall off loose but I could undo them by hand with virtually no effort.
