What....the hell?
Try forming sentences man. It's really hard to understand anything except maybe that you're misfiring.

Your fuel pressure should not be that high. Get that fixed

Re: 420a 2500-3500 Miss Under Load
If the car is NT why in the hell does it have a 255 fuel pump and a AFPR? Make sure the stock FPR is off the car. The 255 pump will overrun the stock FPR but the aeromotive one it will not so you have a problem there.

Re: 420a 2500-3500 Miss Under Load
a new fuel pump is $142 a 255 is only $109 what would you buy?????----
I am not new to the 2G or the 1G so i know that im doing. AFPR gos right in the stock port. So on that note fuel psi is fine. I`m thinking injecter. i have 660cc on the way and I have a trubo for this car but i have to fx the misfire. and yes the 660CC work fine on this car as a N/T

Re: 420a 2500-3500 Miss Under Load
The 255 pump will work fine with the AFPR but you had to buy that also which made the setup cost more than a stock pump. Still not a bad idea since you plan on going turbo. What do you plan on controlling the 660s with? The stock ECU wont controll them no matter how low you run the fuel pressure. You may be able to pull enough fuel with a SAFC or emanage if you run a super low base pressure. But then you may run into problems with the fuel not atomizing all the way.
No offince but it appears that you do not really know what you are doing. There is no reason to run that big of an injector unless your built and/or running megasquirt. I doubt this is the case but please inform us on what your goals are for the car. Back on topic you should be getting a CEL for the missfire. If your not you could try checking the plugs and try to see which cylinder isin't firing and go from there.
