Hey guys relatively new to the forums, lurking for a few months. I have a 5eat 05 gt with a recently rebuilt motor that had a cell die on the battery over florida vacation.
After replacing the battery the car had a noticeable loss in power, so I did some troubleshooting. I bought a GS TMIC, a new BPV, and a new samco bpv hose (due to what appears to be leaks in all three), as well as ziptied and checked many of the vacuum hoses after a homemade boost test. None of this affected the loss in power.
I did some data logs of acceleration and it seems my MAP only makes it to atmospheric pressure, and I hear no turbo spooling, though I'm not sure how loud it will be as it is the stock turbo. My max MAF reading has been 72 g/s
Any thoughts? could my wastegate be stuck open?
