boost?
Ok, on my car when I got it, I put a boost gauge, I was only running 6 psi. I read up on it, and someone was saying 12psi, is where you wanna be. If I'm wrong please let me know. I have the "KKK" so I adjusted the wast gate now I'm at 13-14 psi, and I have no power gain. I adjusted the ALDA as far as it would go thinking i was just lean. please help.

Thanks, Adam

Driving or just revving the engine?

More boost beyond 9psi will not increase power.

The ALDA doesn't affect maximum power, it only prevents smoke off the line.
