24lb injector will support better than 400hp easy.

Get an adjustable FPR, 24's and play with the fuel pressure, start at about 46psi. According to the stang analyzer 58 psi is the setting you should have with 405 crank hp. Of course, that's an estimate. Based on your combo making 360hp you'd set at 46psi. Adjust from there. Although I'm betting a dyno tune would add some serious hp if you are just out of tune.

The 30lbers are huge for what you have. You could nearly run 24lb injectors at stock pressure!! Right now if you don't have your fuel pressure turned way down (which will give you a shitty spray pattern), the computer has to be using all it's ability to adjust the pulse width on the injector. Anyway, your friend may have had a weak injector, or maybe you didn't pull the battery cable and reset the stock computer? How long did you drive it that way?

I think you should be in the 11's with the spray and traction to tell you the truth.

If the head/cam/intake combo was installed properly you can narrow the problems down pretty good.

MAF, computer, ignition, or fuel system (which we know isn't right).

What ignition are you running? If you are running stock, I'd suggest upgrading it, especially since you have bumped the CR.

Perhaps the antiknock sensor on your intake is malfunctioning and the computer is yanking timing like nobody's business?

There are still a lot of variables, but swapping the computer, MAF and injectors should give you an idea what's going on with the data crunching side of things. Swapping the injectors will allow for a better spray pattern and performance for sure. Am I reading your mods list correct? Your MAF is also 70mm? I would seriously think about upgrading to a ProM77 or equivelent.
