Umarex Gauntlet 30 SL power mods

Anyone using the Ninja 3100psi regulator on their Gauntlet 30SL? Im looking at this as a next step to get those 78gr/85gr/90gr and 108gr bt Griffin slugs at the 1000fps threshold or more OR IM looking at a .308 barrel chambering to get those .308 heavier slugs at/ or beyond the Texan .308 velocities with accuracy to boot..
 
@tradecraft6f did you ever install that 3100 psi Ninja reg? if so, how's it going and what slug are you using?
