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,

Vince

as long as afr are stable and you dont lean out you are fine , of course you are making the lpfp work much harder. Depends as well how much power you are putting down. on E50 with stock lpfp i was leaning out after 6k .
