I have a set of mine in my car with approximately 5,000 miles on them which I’d be happy to throw an Autel with data logging capability on and take a drive (sorry I do not have Xentry locally). I also have access to a CLS63 with 63Mo Stage 3 plates and skeleton covers with Ti hardware that I can have @asher63amg throw Xentry on to compare if you’d like, as well as another 507 with well over 100k on the clock with stock components.
As you may know, the accuracy of the actual versus commanded cam phase angle depends more on the state (health) of the solenoids and the leakage rate of the rotary unions, coupled with the accuracy of the trigger wheel/sensor combo than it does the actual phasers themselves ONCE UNLOCKED. After the phasers unlock, the plates themselves ONLY job is to prevent oil leaking internally across chambers or externally to the rest of the engine. With the precise nature of the surface on new plates this is a massive improvement over the worn and leaky OEM components as demonstrated in the video.
You’ll notice also that the feed pressure on ours is about 25 PSI to produce a comparable leakage rate as compared to a pressure reading so low that it does not register on the gauge with the OEM plates to hemorrhage air from the covers.

Here is a screenshot of the Autel tablet with the adjusters unlocked at hot idle (which is the worst case scenario) in the correct position a couple weeks after the install. It was an afterthought to hook it up, as I was troubleshooting a CAN-BUS issue with my E class diesel.
The intake cams are within .02 degrees of each other where the tolerance is 4 degrees. .02 degrees is 0.5% of the allowable tolerance.
The exhaust cams are within .40 degrees of each other where the tolerance is also 4 degrees. .40 degrees is 10% of the allowable tolerance.
I will take a running datalog with video later this week if I have time.

Out of professional courtesy to 63 Motorsports I have said in conversations between myself and them that I will not compare my parts to those from 63Motorsports. I will leave that up to the observer.
My parts are made from AISI 4340 Q&T steel with AISI 52100 reinforcement bushings installed in the high wear area where the pin locks into the lock plate.
The base metal is between 38-45 HRC, and the reinforcement is 62HRC in hardness as compared to the upper 20’s-low 30’s for the OEM material.
They are precision finish ground on a rotary surface grinder for flatness, parallelism, and oil seal integrity.
Tasos torques the cover bolts to 20NM, I find that to be slightly excessive as it can distort the covers (no matter whose you use) I prefer to tighten them by hand using loctite blue thread locking compound.
