I've idled and limped without the HPFP before, and it'll register ~80psi (around that is the lowest reading I believe). The car can be limped, but it'll max out at around 20-ish mph if I remember right. You'll basically be running straight off of the pressure from the gas tank's fuel pump.
In my case, after my build I forgot to grab and stick the roller-spacer in between the HPFP piston and cam lobe out of the old engine into the new engine, so it wasn't stroking the HPFP and was running off of flow-through from the fuel tank pump.

I replaced mine even put the new one and check to see if the roller is hitting the hpfp and everything flowing smooth, it's crazy how my car idles it will got to 500rom then zero then 500-600 rpm then zero least that's the hptuner is showing, so going to unplug everything and check all my connections see if I put sumtin where it ain't suppose to go.

FINALLY FOUND THE ISSUE!!!
The 2 teeth to the left of the flash the tooth under the flash and one tooth to the right of the flash those four r pushed like really not noticeable took 4 rotations of te crank to see and compared it to my old crank that how I was able to point it out, must have happened during shipping, they r not touching the journal but going to pull them bk and see what happens, found a few thread on LS1's and few Hondas where they were able to pull them bk n everything ran fine. Need this winter season to approach faster now so I can get my short block smh..... Budget ballin is killin me. But I found the problem.... Happy bout it

If you're on a stock tune and you put a 3bar sensor everything is going to be messed up. Leave the stock sensors in until you go to tune it
When should it build full boost? And how much air does it flow?
