FX Fix impact & 27.5 gr slugs

[Flyer1944]

I have a stock M3 impact .22 with a 700mm barrel wanting to shoot 27.5 gr slugs at or close to 940 fps.I would like to know if anyone has a tune that would get me close to that speed . My 2nd reg is currently set at 110 bar macro 16 micro maxed out.Thanks in advance.

I have the 600mm, had it shooting H&N 27gr hp @ 970 second reg @135 Max wheel (16) micro I think was 3 and 4 lines on Valve adj.
was getting same accuracy as pellets @65 yards.
