OK, I'm in the process of installing my aftermarket fuel pressure regulator.
Installation seems pretty straight forward. However, when I come to set it what PSI can I go to? The manual states between 38-44 PSI as standard. Can I increase the PSI over 44, if so to what PSI? Also, what PSI can the standard Fuel Pump cope with? Any help would be greatly appreciated. BTW: I have a '97 ST with standard injectors, an Injen IS2040 intake, Denso Idridium spark plugs and Magnecor KV85 spark plug wires. |

One very very basic thing that has been overlooked is...spark plug colors.
They give a very good indication as to whether you are running to rich or too lean.  Also, something to bear in mind is that the standard ECU uses the standard sensors to track and adjust the A/F ratio electronically. So I'm assuming that even with an S-AFC connected (but not set) its the ECU that is managing everything. To gain optimum performance the S-AFC has to be set correctly and IMHB the best way is to get dynoed. |
