You should reconsider it. It will save you a lot of time, guesswork & not to mention paint.
When I first got my Darq I had to play around with the LPR for a while to get it to even somewhat cycle properly. Initially I had a lot of drop. After a lot of blind tuning (no tester) it improved, but it wasn't ideal.
Then I got my tester & it turns out after all that my LPR was still only at 72 psi when it should've been at 85 psi. It only took me a couple minutes to do what would've taken a lot of time out of my playtime to even get close to that level of precision. All without firing a shot.
