Fuel Pressure Regulator, PSI setting ????? Options

[3TST]

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.

I believe unlike you, he is not going to be racing or always looking for that little bits for each part added to win that race.

Why put him through the added rising expense when more can be done before a full tune.

You think just by adding a AFR should demand one large tuning experience?

We all know that different cars have different emission standard to some points. Some cars like to run lean because there are program to produce less emissions. So increase fuel is not always warrant. Just like the wrx aftermarket changes. Soo much is tied in tuning by the cpu, you have to know what you are doing.

Who the hell would like goingthe street running rich. I believe he and other knows what it looks like to be running rich.

The o2 sensor going bad would not trigger the ecu to display a faulty o2 sensor until it is really gone. Why you think that the bigger case like Mercedes and BMW are coming up early stats for sensors.

I personally believe that there is a difference in need for race tuning and street tuning when advising someone.

I just you should take him under your arm when he has done all of these dynos and let him have your successful career.

Nice talking to you
