Can you start over and tell us if the engine stalls or what the problem is? ABS light or?

Lie down test fail. Inject test drop quicker than you expected.

Ok the leak down test is a little different than I remember. It's been a while for me. But here's what good old Google turned up for me: http://troubleshootmyvehicle.com/gm/4.3L-5.0L-5.7L/testing-the-spider-fuel-injector-2

So how fast did the pressure drop off?

A failure here indicates a bad fuel pressure regulator or a bad fuel injector. Both are common.

Also to add. The computer is on flashed so that's why it's running like a supposed to. No ABS light so far. No limp mode so far. Again thank you for everything.
