Just thought I would update everyone on what i've been doing with the diagnosis.
I installed the Neuspeed K04 T.O.P., and the Neuspeeed Hi-Flo Charge pipe. The green gasket was in good shape with no tears. I tightened up every connection from the turbo to the throttle, then ran a boost leak test. I had no leaks up to 15psi of testing, but every time I would go above that, my attachment would blow off of the coupler connected to the turbo.
I didn't hear any leaks and ran my hand on every connection I could find and did not feel anything. The only time I felt a leak was on the hot side of the intercooler-T.O.P. where the green gasket is. If i would try to shake the T.O.P I would hear a hiss. I re-aligned the coupler with the retaining ring and did not notice a leak afterwards.
I also confirmed that there is an in-line filter connected to the Podi Boost Gauge, so I think the sender is in good shape. I noticed that the gauge occasionally "sticks" when I rev the car or just during normal driving.
I took it out and did some pulls, I noticed it boosted on average 2psi highe (17psi in 3rd opposed to the original 15psi, and about 19psi in 4th instead of 17), but it still not as high as it should be.
Here are some questions that I still have
1. Where are the most common boost leaks located? I didn't hear anything on the PCV system leaking. I also confirmed the PCV system is working properly by pulling the dipstick when the engine is running. (the car runs very rough when this is done)
2. Is there a way to see what APR file you are running? I took the shops word that it was the right file when I bought the car , but I wold like to double check this.
3. Has anyone experienced any Podi Boost Gauge failures?
Thanks for the help guys
