That is a lot of fuel pressure. I have a slightly less agressive combo than you and am running 42psi with vacuum. Stock pressure is 39psi with vacuum. With correct sized injectors, you should be able to basically run stock fuel pressure. If I were you, I would turn the fuel pressure down to about 41psi with vacuum, get a wideband on the car and do some tuning. Do you know if the chip you had was burned with that fuel pressure setting in mind?
I answered that question for you in a PM not but just a couple days ago.
Thats why it pi$$es me of when you come on here and say we wont tell you stuff, WE DO AND YOU DONT LISTEN!!!! Just like plug type and gap.
I give up- anyone else wanna try to help him? Have fun!
Maybe Summits tech guy could help you out?

Wasnt the chip burned with the 24's and no FPR? If there was no FPR that is WHY the chip was burned- and if there was a FPR then there would have been no need for it.
Start from scratch, take out the chip- adjust the fuel pressure to the spec I gave you, and see what the wideband says. You can make all the adjustment you need with timing and FP now. The chip was likely a bandaid for the FPR.
And to clairify, the reason you were told that was BECAUSE the advise was offered before and you didnt listen. There is a point when you just have to give up. I guess its true, you cant save them all.

I have a ? on fuel pressure when running the stock computer.
I read in MM&FF or 5.0 that the adjustable fuel press regulator really does not work, they said that it will work for a short time (Like adjusting on a dyno) then over the course of a few days the computer will adapt to the higher or lower pressure and everything will be the same again. So if you are a little lean and richen it up and go back and test a week later it will be back to what it was.
Then on the other hand you always read in the mags where they install an adjustable regulator and then mess aroung with pressures. ?? They contradict themselves!!
So do tweaks really last? Does the computer not ever adjust for say a higher pressure??

You got an answer to you post in 5.0 Tech
You even answered a fuel pressure question here
This one talks about fuel pressure with 24# injectors
Another one about fuel pressure and 24# injectors
And another
And another one again
And one last one
Easy, you just have to search the 5.0 Tech section and you should find answers to most of the basic questions like that. Or just PM Jeff 2.
