karl. Posted April 7, 2014 Share Posted April 7, 2014 I recently just fitted a zisco rail and a rrfpr so I have done away with the standard fpr. How do I go about setting the standard fuel pressure again to get me to the tuners? 2.4bar at idle with the vacuum on or off? On would mean the fuel pressure at idle is always 2.4bar and off means it will go down to roughly 1.7bar at idle? Suppose I have just answered my own question but I just want to be sure wether its 2.4 when the engine is in vacuum or when its at atmospheric pressure eg 0psi Thanks Quote Link to post Share on other sites
Zeldoz Posted April 7, 2014 Share Posted April 7, 2014 Mines 2.5 all the time. Quote Link to post Share on other sites
