Not so much doing it for a power increase as I am aware that a bridge is overkill for the 450hp I'm aiming for.
Can I bridgeport it if its already extend ported?
Are turbo bridges quieter then n/a bridges?
Does it decrease turbo lag? (heard even less bottom end power but more midrange and top end)

If you have a look under my web page on water injection you will see a 13B bridge port RX2, this makes around 730bhp on ~27psi as a road car.
I have data of this car recorded on my VBOX equipment at a local circuit track and overlaying the acceleration on the main straight for ~600m (starting off in second gear to a variety of other car I have tested) it paints the picture of power band, outright power, response) a dyno sheet tells you little about this in reality.
Have heaps of data of another FC with bridge port and GT35R on same track and the acceleration is nothing exciting nor is the response, this was done and tuned by a Sydney workshop running a haltech recoded on the same track day too.
My tip to you is leave it, maybe post up some pictures of your ports and I can tell you some more information from there, but porting anymore in most cases will send you backwards, turn the car into an unwanted attention grabber, and not make it any faster in most cases.
