54095, 8-injector tuning/ idle fuel pressure
Posted by pn0ymahal, Aug-15-03 05:29 PM
right now my idle fp is 47psi i notice when im like 45-hmmm 65mph i notice if i let my foot of the gas my base fp goes down to 42-44psi at thoses speeds.. just wondering if thats ok ( i assume since im on the go its ok and all ) or should i increase my idle fp up a few psi so when im at 45-65mph it wont drop so low?
my idle fuel trims are both within -/+3%
thanks

That's fine, the fuel pressure is lower there because when you let off the gas on the highway you get more vacuum. More vacuum = less air = less fuel. Don't worry about it.
