Regulator damged?

[Milf Dots]

So I very recently installed the huma transfer port and the FX slug power kit into my .25 Impact M3. Upon installing these new additions I had to remove the air bottle quite a few times because I was just starting to learn the inner workings of the gun. So after I ran into a bit of a problem with my Regulator 2 pressure not giving me a reading, I called Utah Airguns and was advised by a Tech over the phone to remove my air bottle and take a 2.5mm allen key and turn counter-clockwise until it gently stops. Which I did, and as soon as i re-attached my air bottle the Regulator 1 pressure was reading 250 bar. After about 2 minutes, I removed the air bottle again and readjusted the Regulator 1 to read 160 bar. My question is, Did I damage anything inside the rifle? Because it states in the owners manual to never adjust your regulator pressure over 170. And...well it was at 250. However...I did NOT shoot the rifle, nor was it kept at this 250 setting for a long period of time. Im just kind of pissed off that I was advised to do this by a so called "tech" who should know better? When it clearly states to never go above 170 in the owners manual. Am I being overly worrisome? Or am I within my right to be somewhat ticked off about this?
In the picture below is with the red arrow pointing to where I made the adjustment. So you can see for yourself. Please, any and all feedback is very much appreciated and very much welcomed.

Nothing wrong. Don't worry. Everything is fine

What the tech should’ve told you was to adjust thd second reg by first(no air in Gun)CLOCKWISE on the reg screw all the way to a SOFT stop.
Then back it CCW a whole turn or two. Two turns will put you at around 80 bar. Connect your tank and then turn CCW to raise the reg to your desired setting. I like to go up 20 bar then fire a couple of dry fire shots. I also stop short 3-5 bar of my desired setting, and take about 3-5 shots, each time watching how quickly the needle responds and settles. Once I see it is for sure settling at the 3-5 bar less, then I minutely turn the screw CCW to my chosen setting, then fire off a couple more to verify it lands on my setting and stays put.
Also, me personally, I don’t like to lower (turning CW) the pressure with air in the system and doing the dry fire thing like FX says it’s ok to do. I’ve tried that and if you do it enough, you’ll start developing creep as the Delrin tip of the reg piston is slowly getting damaged. But, again, that’s my take on things as it’s happened to me. So to lower reg pressure I drain the gun down and start over like I described above
