At 16-17psi of boost the BP turbo kit starts to have back pressure/drive pressure issues. It's due to the exhaust manifold to turbo pipe size. It is also due to the stock headers themselves if you push the power up higher to 20psi of boost settings. The turbo size is also too small. At 17psi of boost with the BP kit the intercooler is not large enough. The IAT's go through the roof. 150+. So, the max safe whp you can make is around 650 to 700whp maybe. My friend tested all this. That's how I know. He has a custom turbo kit now.
