Recently, my car started performing pretty bad when I would hit the accelerator in the 2k rpm and up range.
I have a boost guage installed and before this problem, the boost would regularly spike up to 20 psi, and settle around 15 for hard acceleration. It would sit at around 5-6 psi when cruising on the freeway.
Now that this problem started, Im finding that the boost has a really hard time going up. On hard acceleration it slowly creeps up until it hits about 9-10psi max at 4k rpm. Regular driving produces no boost at all. Hiting the accelerator anywhere above 2k rpm will do next to nothing and the car will accelerate rather slowly compared to what it used to do, probably because there is almost no boost from the turbo.
I can hear the turbo whistling pretty nicely while accelerating so I don't think theres a problem with it. I also disconnected the MAF, which decreased performance even further.
Does anyone have any ideas as to what it might be?
