ur logging image looks typical - but more details r needed - looks like u did 2 quick pulls 2-5 K each... but it does look normal. looks like u peak around 16.5 to 17 psi. there are a lot of variables that are not known - need the csv.

i think i fixed it..the line running to the tank was pinched so i had to put a spacer in between the line and the interior trunk piece.. it wouldnt let me upload the csv log but heres a pic of the log
