Just finished installed last night, this morning I filled up with 6 gallons of E98 ( I don't have E85 ) and I able to peek at 20.5psi and steady at 15.5 psi all the time. It Was fun but wish It can hold at 20 psi
terry is the man. He even replied to my question at midnight last night. Could not be any happier. JB4 and terry thumbs up
