Broken in but stock except for trigger, I was getting about 900 feps from my bosses S1K with Superdomes. That's almost 15 fpe. I was getting just over 14 from my gas rammed CFX. HTH.

does not fit the bore well, you may even get a little below 13fpe.

at 855 with CPL's(7.9) and 835 with JSB Exact's (8.44) with a used JMaccarri spring at Airguns of Arizona, exactly what they predicted it would shoot. The oe spring broke at 2500 rounds, then I tore it down for an inspection, polish and lube. Shimmed the guides with shrink tube to fit the spring, polished the spring ends and put SS thrust washers front and rear of the spring. Stock seal was in good shape, so it got re-used and the above is what I came up with.

Beeman Silver Bears (7.10gns) for 15.7 fpe out of the box. After some internal work, and Rich/Mich guide kit, and keeping same spring and seal, it started, and still does a ten shot string over my chrony at avg. 1020fps with 7.10gn Silver Bears for 16.4 fpe. AND NO it is not Dieseling! This gun was Hot out of the box and I only made it better. Now if I could only make it more consistently Accurate! Curiously enough, shooting 8.35gn. Beeman FTS, it shoots it's best, but only 13.7 fpe with the heavier pellet. Something to consider when using fps and fpe comparisons of the relative power in Air guns. The pellet mass, size, shape etc. affect the guns total performance in terms of Power and Accuracy. Everyone knows about the accuracy correlation to pellet size/shape, but the total FPE correlation was an eye-opener,(at least for me).FWIW.

accuracy, but I'll bet your spring and front seal will last longer shooting heavier pellets. Have you tried JSB Exacts in 8.44? They're the most accurate of the domed pellets in my S1K. If you're looking for fps, like most manufacturers seem to go for, light Raptors or some of the other non lead pellets will probably get a hottie like yours close to 1100fps, but who know where they'll end up. I like my 1" or less groups at 45 yards shootins JSBs at 835fps. just my 2 cents.
