I'we buld dozens of 500bhp BP setups over 15 years. Why would I do that?

If you are running e85 and high base fuel pressure and a 1:1 FPR, plus a lot of boost puts your pump output up into crazy amps territory. Probably ~15A or more. I've never measured, but I bet a stock pump tops out at 10A.

Kinda silly to install a huge pump on stock wiring, not too hard to add a relay with the battery being where it is.

I don't think bigger (16A) pumps even work at all with stock wiring...why would you think someone being so stupid to run massive pump with stock wiring?
Much more common problem is fuel pump filter sock collapsing

I don't pick up on sarcasm well, my bad...

I think solved my problem. Fuel pressure sensor had a worn connector. They are right behind the radiator and somehow hot air make that broken connector to read lean....

I measure fuel pressure. My dead times for the injectors (FF640s) are scaled by fuel pressure differential, which is calculated field in my Elite 1500. I monitor/log both fuel pressure and FPD via CANBUS output. I also have some engine protection setup for fuel pressure.

Need help where to wire the 100psi sensor into MS3 - I have an options rear connector that has 2 analog channels MAF for default Analog 1 or Analog 2 seems also open. Does this channel receive the signal Pin C and 5V from H and Sensor ground pin A? Once wired is the next step tuner studio custom ADC? Any tutorial on ratiometric .5-4.5 settings and calibration ?

Use generic sensors and the linear scaling in that feature.

Is shielded wire needed for fuel pressure sender ? Did not think it’s sensitive enough but thought of checking for good measure. Thanks
