You won't see those numbers like that. With FI it's not just the turbo or SC kit, you need supportings mods, even at low boost. Now it's not impossible to meet those numbers, but it will take a bit more than 5k, plus time to tune and work out the issues that arise with FI. Now the 3.8 does handle boost well bit it still will need forged bottom end to reach reliable numbers. My friends had blowby at 8psi on 3.8L stock bottom end before he built the forged motor in there now and reaching 500+hp
