Something is very wrong. Your intake will flow up to 400hp fine, it's not that. The heads aren't the best...but they're not e7s, and the cam is a decent grind. 24lb injectors are good for 350 to 400hp. And from what you're saying all the other components are there. Is it an AOD or T5 car? not that an automatic should drop you down to 248hp with that combo, you should still be in the 280-310 range depending on your tune. Get an adjustable fuel pressure regulator and bump the timing to 12* for starters. How does the car run around town? Idle rough? bog at any certain RPMs? Pull a plug or two real quick and check out the color on them to make sure you're not super rich or leaned out.
