i'm feeling a little dense right now, since i haven't driven my car in a week i think i'm losing touch lol...

how is it that on some logs, people have shown fuel pressure spikes of 2100+ psi if the sensor only reads up to ~2030 psi?

Or is this a separate sensor?

Were those logs from standbacks? Based on SSInstaller's responses in my thread I think the sensor it self is capable of reading higher pressures, but for some reason the ECU is clamped at 2073.9.
