This failed after 8 months of normal daily driving and caused over $2k in damages. Please think twice before you install parts of questionable quality.
Aaron, excellent explanation! Yes, the rear O2 sensor is unplugged, I've read about the ECU running rich. I wonder what's going on there too.
I'll upgrade the HPFP and post a follow up. I'm sure this info will useful to many others out there.

What are the signs your fueling is weak? I'm seeing rail pressure drop around 5800 rpm with higher corresponding injector time. AFR is maintained. What indicates weak HPFP vs LPFP, or both? I'm on a base stage 2 file, about to get custom tune and I want to address anything before revisions...
Try this to reinstall:
1) Put the strut spreader all the way to open the knuckle as much as possible. This temporary as it will prevent the struct from achieving full insertion.
2) Position the strut next to the opening and loosely install the 3 top bolts
3) Use the bottle jack in same position...
Decided to try something different, I used a bottle jack to separate the struts and it literally took 5 mins each side.
I know someone will tell me this is wrong. But I did springs on two cars in less time than one.
