Low fuel pressure’s and injector cutout at wot

[TheLeastReliableN54]

drove my car hard one way (no issues). Parked it for a while, got back in and floored it from the bottom of 2nd (warm) and it sounded like it hit a rough fuel cut. Car starts sputtering and is in a limp mode. Turned the car off and on and it drove home just fine

Anytime I go wot now it does the same thing
And it seems to be taking longer to crank.

Since then I’ve seen codes:
29DC - DME: Cylinder injection cutout.


2A2D - DME: Fuel low-pressure system, fuel pressure.

New-ish stage 2 lpfp btw (17t 91 tune)
(Included a data log of a pull + start up)

Sounds and looks like your HPFP. That being said, your low fuel pressure is also low, its reading at about half of what it should be (50-70psi), so could be starving the HPFP. You will need to do a proper log. WOT from about 2000rpm in 3rd, try and include the shift to the 4th.
