Without the tune 260. With the tune depends on the tune.

You will be at exactly 308 hp and 339 ft lbs of torque. I guarantee this, unless you have a hidden "CSS.NET" sticker somewhere on your car. You will then be around 1000hp.

You would likely net around 280whp and 300-310wtq with the mods. Your torque might actualy be down a bit with the IC and 3" exhaust. And if the Intake is scewing fuel trims you may be getting KR which actually limits your HP. If tuned for pretty much what everyone else said. 300+whp and 330+WTQ and only up from there depending how aggressive. Im assuming you will be running a conservative 22psi?
