Yea, it's not leaning out because most likely your short term fuel trims are maxing out trying to keep the demanded lambda(LAMBASE in SCT)... But once your combined LTFT and STFT are +25% the car will close up the throttle to keep from running out of fuel.
And when your fuel pressure drops that low your car starts to have a hard time dissipating heat in the cylinder...
Just keep an eye on it...if your running that close to the edge of the fuel pressure and your are seeing knock then you could run into some unfavorable issues.
