Intermittent miss up to 2k and idle when warm NA-T

Update!

I bought a new Mac tools pro fuel pressure test kit and it had a banjo bolt adapter that I hooked into the top of the fuel filter...

Results- with Vac line disconnected and plugged 51psi. Factory spec 38-44

With vac line hooked up 42psi. Factory spec 28-34

1500 rpm 55psi with vac line hooked up. That is out of factory specs so I will be replacing it.

I apologize for not adding the info about the stock distr cap. I reinstalled the original with no change. Although I did have to change plug wires back to OEM as well. So I put the 4 runner stuff back on and doubled checked that the timing is at 10btdc.

Is it possible that the added pressure from boost could damage the factory fuel regulator?? Should I stick with OEM or go to an aftermarket in your opinion.

My BOV is an HKS SSQ that I bought a recirculation nipple for so it has been blowing back into the intake post MAF, pre turbo!
