Get an EGT gauge and a wideband O2 sensor and find out for yourself on a track...

This has been talked about a lot, and the answer to your question lies on a dyno. I feel that the injectors are the limiting factor in your setup right now, as they are only safe to about 245-255hp at the wheels. Even that isn't accurate due to not knowing how well the ECU is tuned. To safely tell you need to get the car on a dyno w/a wideband.

Speaking of widebands, my friend just got the AEM UEGO and I am in love with it. Definitely coming up in the near future.

Ehh, I was in a pissy mood

You keep adding fuel and boost untill you can't keep the EGT or O2 safe or your times slow down.
