Power seems low- SpoolinChevy made only ~40WHP less with a stock 4.8 with just 6psi from a 62-1.

I get really paranoid with things, and since I wasnt able to actually see how hard the fuel pump was working or actually is working now, I asked allen what would be a good way to alleviate some of the pressure being put on the fuel pump, and he said a bigger rail with a bigger crossover is a cheap mod to do. I dunno it was just an idea

My 5.3 with 6psi made 460/517 (60lb injectors at 52%)
On that much boost, #1, your flirting with disaste stock pistons, #2, it should make WAY more power, I was shooting for over 500rw on 9psi... I had a nitrous cam, that was really wrong for the setup too, so I don't think that was helping much.... Front mounted MP T-70
Just a comparison...

Timing was a partial issue, he could only do so much before. He was showing me the maps and so forth, I kind of understood what he was showing me at the time, but now its somewhat lost me. I know that on the dyno he was pulling 23 degrees or he was at 23 degrees. I cant remember so take what you may with that last sentence. I just vaguely have a photo image of looking at his laptop. No this wasn't on a mustang dyno. I forgot the name of it, because I asked him about it and what it would compare to, and he said this dyno doesnt inflate numbers like others does.
