You just need to dial in your MAF with the sliders. Your settings are kind of crazy right now and your BoostEst and AFRs show it.
The highest MAF reading I'm seeing is about 1100Hz. You are adjusting 1200+ for no reason IMO. Even your BoostEst and actual boost is way off because of the added MAF signal. You need to zero things back out and add global fuel if need be. Adjust and dial in both your MAF and injectors.
Yes, closer to zero is more fuel. Use the MAF sliders to dial in the MAF(match BoostEst and actual boost at or near 5500) and use the global fuel to dial in injectors. Lots of fine tuning besides that but that'll get you started.
On a stock cams/intake manifold vehicle 5500 seems to be the most accurate in terms of ve of the engine. After that you'll notice the BoostEst will slowly drop even if actual boost status stays flat. At this point you really are just adjusting MAF sliders to keep your AFREst a close to actual AFRs as possible.

What fuel regulator are you running with that fuel pump? Might want to verify that your holding pressure correctly.Can someone help me out, I took my surge tank out and now am just running from the intank pump only. Pump is a Aeromotive 340

Did you end up figuring out what was causing your sliders to go so high? I might be having the same issue and I'm digging through the forums to see how people handled it.I have the one below, with a different gauge. With my bosch 044 in a surge tank the needs holds steady, with this pump it jumps maybe 1 psi while idling.
I'm not sure what it is doing while i'm running. Can't tell.

I have an Aeromotive 340 in the tank so it should have no issue. Charts show it flows just as much as the 044.
