My fuel pressure idle with vacuum hose on is 325 kpa or 46.5 psi vacuum hose off 405 kpa or 58.7. I did the searches and went through Ashs dyno dissertation but still confused. At WOT 102 kpa or 14.8 psi of boost it only rises to 375 kpa or 54.4 psi plus when throttle closes it goes up 10 kpa for about half a sec. This just doesn't seem correct so please tell me if I'm mistaken. Thank you. Craig
