Running 190s on Eric's extreme street. I have a stock system with updated FPR spring and 6.4l banjo bolts. My fuel pressure stays at 68psi until I give it half throttle and it will drop to 60-62. That is normal driving and passing people, taking off, speeding up, etc.... I tried the WOT once and it plummeted to 20psi. My mpg is 17-20 too.
Next, I am going to upgrade the feed lines to the heads, then a regulated return. I just want to see if the stock pump will be able to keep up with the 190s if given the chance.
