115fpe vs 150fpe real world?

Im torn between two tunes on my uragan for hunting. Its a .30 cal. One tune at 165 bar shoots very accurately at 150 fpe, but comes at a cost. My power adjuster I made for the transfer port doesnt really work ( pressure makes it move) and the hammer hits harsh and is more violent. Drives tacks tho! At 115 bar, It makes 115 fpe, everything works as should and is super smooth and just as accurate. As a bonus, it will shoot pellets at 510, 750, 910, 1030fps. Which is pretty fun for plinking and hunting. So I guess my question is does anyone really see a major disadvantage of shooting 35fpe less on coyote size game out to 100 yards? Im 50/50 on it. I also have a .35 Im going to start tuning which might be better to use on bigger game than the 30 cal. Any thoughts?
 
I would say since you have the .35 I would keep the .30 at 115fpe and shoot it like it should. I have a .30 that's at that fpe and use the .35 for the higher fpe. Just because you can doesn't mean you should especially with the downside's you have stated.

Tune that .35 and don't stress the .30 out. You can still take coyote size game with the .30 and that all so important shot placement. Have fun and enjoy...
