I'm not looking at drag racing it right now or anything so i would like to keep it running on the twins right now. My question is: How much power could i get on the stock twin turbos and what would i need to do to achieve that power? I'm looking at around 600 crank horse power at least. Please let me know what you think. Thank you.

The most power you could practically achieve out of the oem twins depends a lot on the condition of your turbos and your engine. However, there's no practical way to get 600 crank horsepower out of the oem twins alone (i.e. without adding nitrous). If your engine and turbos were brand new, your max through a 6spd (not sure if you have a 6spd or an auto) would be about 485rwhp (570 crank hp) ... and even that is only after a lot of "bpu++++" modifications. To get on your way, you'll need to start with basic bpu, which is described here:

Note: Although that link shows an exhaust as the first bpu mod, an exhaust won't affect the horsepower until you get into the bpu++++ range. The item that's missing from the list is adding a boost gauge, which is critical to keeping your engine in good condition and letting you know what octane of fuel you need to run (based on the boost levels you've chosen with your boost controller). Note however that some ebc's do display the boost level.
