Fuel pump Failure At 185 MPH

[Weyne Masters]

Couple days I go I was in Roll race event, 1 mile.
During accelerations in 4 ,5 and 6 gear I've realized the car hesitate a cell after 7,000 RPM my AFR was 11,8 in read line and after I get 185 MPh I had Fuel pump malfunction,and also Limp mode.
I've hock the Code reader and it's gave me a fuel pump high RPM.
No Misfire code!!!
I am in doubt between some things.

Sparks are Brand New
Primary O2 sensor new

PM Drew aka DLSJ5 to ask about a high power fuel pump solution. You may be at your pump limits given the high boost you are running. I think a few of the built engine high power people with superchargers making 650+ rwhp made some sort of pump change due to issues, but I do not know the details.

Did you at least win?

You're on a high mix of e85, correct?

That time I had E25 and race fuel!

I had this when i first installed my S/C. it was the LPFP i believe. ESS was very helpful in diagnosing and replacing it. I would swap that first. its about $90 IIRC, and takes all of 10 minutes.

LPFP what does it means ,and May you let me know the Part Number?
