To test the fuel pressure properly, I connect to the shrader valve that is right on the fuel rails?
Ok, I connected FP gauge to the shrader valve on Fuel Rail.
Here are just some random notes that I took while on the test run. Most might be USELESS but here they are:
Car off: 38 PSI
Key On: 48 PSI
Reverse (0 MPH): 43 PSI
Drive (0 MPH): 41 PSI
WOT from low speed: 59-60 PSI
45 MPH: 45 PSI
While RPMs drag down to 2k RPM: 40-60 PSI. Like a propeller on a plane.
60 MPH 0% Throttle: 45 PSI, Apply throttle: Lowers to 40 PSI then jumps back to 45 PSI.
70 MPH, 2K RPM (Torque Converter Locked In?): 40-60 PSI. Jumps between like crazy.
70 MPH, 2K RPM (Torque Converter Locked In?): 48 PSI steady. It'll be steady once in a while, Usually jumps around between 40-60 PSI.
50% Boost: 55 PSI
50% Boost, Car was only at 3K RPM after I applied more throttle from 2K RPM, While TC was locked in. <-- might be a little confusing.
And there it is folks.
At WOT, PSI was always at 60.
