once you get it all hooked up I would take it to a dyno and have them hook up a wide band o2 sensor and they can tune it to higher boost levels if possible.
The reason I say this is because I had mine dynotuned and my stock injectors were maxed out at 6 psi.
BUT there is one guy I have talked to who said he is running 13 psi on stock injectors.
I think the average is around 8-10 psi though.

I was running 8 psi on my car for a long time with stock injectors. I used to have really bad high EGT problems though. Ever since I took off the FCD and installed my 440's my car runs super cool. I can make long hard highway pulls and it doesnt get hotter than 1550

thanks for your help guys. i am just getting it all ready to go. the block is getting bored as we speak. je pistons and eagle rods should be good for 15 + certainly cant wait.

I can run really rich at 8 psi if i wanted to. Some like Strauss have run 13 psi and have run rich at that. How, i have no idea. 10 PSI is a good safe limit IMO.

I'm sure you could probably run 10-12 psi on stock injectors every once in a while. For a daily driven car, I wouldn't recommend going over 8 psi, if you want your engine to last.

Mine would max out at about 9psi.

I'm running about 12psi right now on my stock injectors. I am right on tune with my EGT's and A/F readings.....and at 7000rpm on the AFC I'm leaned out 8%. If I leave the AFC zero'd out, I run pig rich. My car is a freak though and even I don't recommend doing more than 9-10psi. But on the other hand, if you have all the necessary gauges, and they are reading so that you are rich at 10psi, by all means crank it a bit :) Just BE CAREFUL!!!!
