I'd recommend a fuel pressure gauge. Then you can see if the pressure is starting to fall off.
And autotap or some monitoring device, to watch injector pulsewidths. Then you'll know if you're maxing out the injectors.
When I went over a 120 shot, I needed more fuel. (that was on the v6 pump though...) And I bumped the injectors from 22's to 24's. That worked up to a 150 dry shot.
I've still gotta go through that whole exercise with the LS1 after the swap though.

Guys, he has a 02.
That is 28.8 injectors good to the neighbourhood of 550 rwhp
And the stock fuel pump is much stronger than pre 01.
5177 kit has an inline rail FPS so if pressure drops it will shut off. The only danger is an injector failure or going over the injector capacity.
And with stock cam, I seriously doubt he is putting down that much.
Please don't give false info if you are scared to do it yourself
Like I said monitor and increase a bit at a time.
I've shot with no jets for over six month now and my injectors are only at 92%

now who's giving false info
I specificaly stated I didnt spray higher than a 125 shot on the stock fuel system not that he shouldnt. Any searching in the fuel section will plainly show that nobody thinks the stock fuel system is good for over 450rwhp and many of the Experts that post in that section claim the stock system is not rated that high. Does upgrading my fuel system make me a scaredy cat or smart, because i want a cushion to protect my investment

It depends on your tune (AFR). If properly tuned you won't run rich and max out your injectors before it's time.
It is very wise to protect ones investment, but that wasn't the question here.
The question was can he safely shoot 150 dry with his set up. Properly tuned and monitored, he surely can
BTW I like your 2 stage. Did u swap for a bigger noid?

NASTY HAWK, I see in your mods you say you have an LS6 intake. You didn't swap your original did you?
Because if you did, you went backwards. the F-Body 01-02 intake is actually flowing better than the LS6 (By a tiny margin). Although almost identical it is a different part #. just FYI.
