my WOT logs with stock LPFP logged 4 line items in the 50's (all rest in 60/70's) but never dropped below 52. Was told its normal to drop below requested PSI @ 72.48.
So does this mean my LPFP is good (for now?). There is just too many problems i have seen/read with a booster pump solution. If my LPFP is running fine, why should i go with a booster pump? Is it just a matter of time before my LPFP takes a dump? Just trying to fully understand the risks involved with my setup.
thanks,

IMO if your LPFP is meeting 50psi minimum it's not getting its ass kicked. If it falls below that it'll start to drag HPFP PSI down with it. So if your not running tight on fuel trim, and AFRs look good, I think 50PSI as a minimum LPFP PSI is OK. I've only recently started to mess with E85, but that's what my experience has been.
