Got the cats of my car today

GOOD GRIEF!!!!

That has turned this car into a super monster. Runs cooler, sounds meaner, makes a ton more power....all with no increase in interior volume. I highly recommend this mod.

When you have true dual exhaust installed that will also increase your hp. I still say that you need to check the vacuum line that runs down to the wastegates. My twin tubro had the same problems that you have. Cleaned out the lines and the boost returned to normal with minor adjustments to the wastegates.
