That's pretty close to the setup my last car had. It made 444.4 hp on my highest "safe" tune but I dialed it back to 417 hp. At that tune, it ran 11.07 at 126 and change in the 1/4. My best advice would be to dump the FMU and the 38's and get some 42# injectors, 50# if you would like a little headroom. Get a good dyno tune and a chip and you should be golden.
