Hoping to see some logs with E30 in colder weather to see what these OEM replacement pumps are capable of, or if we still have to go with higher flowing aftermarket pumps.
I run E30 on the stock HPFP year long and never had an single issue with crashing due to weather... not sure why this upgraded one would.
