When I used to have the PMM single port on my G17, there was definitely a noticeable difference. Trying to find a holster was a pain, in the end I sold it and then bought a Zev RMR cut slide because they stopped making the 17 MOS Gen 5 and all I had was a 17 non MOS and I don't send slides out to be milled. I plan on getting the tungsten rod for it at some point, but it's already flatter than my 45 IMO, there's definitely a difference between rod and spring size.
No, unfortunately no timer. Whether or not I personally feel the differrence is worth the effort will be totally subjective, on my part.
