Possible fuel issues please help
Ok here's the issue, it's seems hard to explain but I'll attempt, the car runs great for a period but then drop face first, won't pull any kinda rpms, stutters pops and so on, sometimes I can feather the gas sometimes and it'll clear up for about 3 seconds or it won't help at all, then it comes right back, my fuel pressue gauge will hold even till this thing happens then it fluctuates by 20 psi or more stupidly fast. It's stumping me. I'll try to provide more info as I get figure out how to put it into text.
Thanks
Thanks

When you rev the motor your fuel pressure should drop a psi or 2. at idle is SHOULD be about 59.5-60psi.
I also changed the title of the thread to get more insightful people involved. "WTF is up with my car" doesnt attract most people.

Yea the thread title in hindsight wasn't a good one, and thanks for the input everyone I figured it was a pump or injector issue but the odds of my injectors going bad at one time were nill, I'll get a pump today. Any one I should get? I'm running a lt1 pump right now

Walbro makes a 255 litre/hour gerotor type pump that works very well and can keep up with your future engine plans. Check the sponsors.

ok did a little more work on it tonight, seems like when I pull the vacuum line off my regulator the motor evens out some. it also backfires and pops out of the exhaust, lean fuel mixture. Brand new pump and filter.
