in a word....awesome!!! Got it back the other day. First look out of the box I could see the Gold trigger staring at me. Cool! Next, I picked the gun up and realized the loose right piece of the forearm stock that came with the gun was now tight thanks to CDT. Now the gun was clean and shiny and tight. Here is the pre-tune story on my CFX.
Cocking the under-lever was rough, noisey and uneven. Heavy recoil and "thwang and big vibration" while pulling the trigger.
Trigger pull very hard and unpredictable. Although the CFX only had 400 or so pellets through it at the pre-tune stage, I was hoping for some better groups at that point with the best shooting pellet at that time. I was leaning toward the JSB preditor.
Ok,..now for the post tune from CDT
Cocking the under-lever was much easier, with very little noise, (if any), and smooth as glass, from start to finish. The heavy recoil, thwang, and vibration is GONE :p . The new GRT trigger is.....

:p ...AWESOME!!! What a difference!!!! I can't begin to tell you what this trigger has done for this rifle. Again, just like the rest of the tune, the trigger is as smooth as glass. CDT also includes detailed specs on your gun including gun care, trigger specs and your guns chrony results before and after the tune up, and more.
I had to post a pic of my CFX from CDT below and add a few pre/post chrony numbers too. If you want a NEW air rifle...sent it to CDT.
The difference is not night and day,...but midnight and mid-day!
BTW...I shot 4 different pellets through the CFX today. JSB preditors still won the day. I will post more results after my liberated CFX is " broken in again".
