L loserpunkx182 Senior Member Sep 26, 2005 #1 is says it's set at 40psi from the box but is that 40psi with the vacuum hose on or off?
L loserpunkx182 Senior Member Sep 26, 2005 #2 called aem..shoulda done that in the first place lol...it's hose off
ripperbone angry bear Rest In Peace Sep 26, 2005 #3 40 psi with vacuum line on and when you hit the gas, at idle it should be around 30 - 35 psi. at least thats what my fuel pressue gauge say's, i just left my aem fpr stock from factory

reikoshea HS Troll...And Mod Moderator VIP Sep 26, 2005 #4 well AEM seems to disagree with you ripper
P posol RETIRED Sep 27, 2005 #5 i don't agree with aem either. all fpr's need a vacuum source. honda ones are 1:1, meaning they don't rise disproportionate to vacuum (like fmu's do with boost) it should be about 35-40psi at idle, and as you get more vaccum from more rpms and throttle, it raises the fuel pressure a little bit
