    is that something that u have to live with? My Fx reg first shoot were 60 fps lower, so i sent it back to Fx as soon as i got my huma reg.

    with huma reg first shot is 32 fps lower.

    1 more thing is when i installerat the huma setting was 128 bar, now when i took it out the setting was 130 bar. Fps was a bit high, so i lowered to 121 bar now.

    Don't know how long you have had the Huma set up on your FX,  but it does take a few hundred rounds for the Huma to settle in and give consistant  results … from what I have heard. Sooo if that Huma is new I would shoot it a little while and if it doesn't please you then I would start making adjustments.

    The first shot from a regulated gun after storage for any period should always be either at regulated pressure or higher than regulated pressure(assuming in most cases, bottle pressure is higher than regulated pressure).

    If regulated gun was stored away and then shot at a higher room temperature from when it was stored, you should expect the first regulated shot to be at a higher pressure/fps. This is because the regulator has no way to dispel the pressure build up from initial regulated pressure as temperature builds up in it – as temperature increases, pressure increases. 

    Conversely, if regulated gun was stored for a period and then shot when the room temperature was at its lowest, then one should expect the pressure to be at regulated pressure, assuming no creep.

    You have a regulator creep/leak issue if your regulator creeps gradually towards bottle pressure over time during storage, or if the regulator takes a long time to get back to set regulator pressure after a shot, or it just does not regulate at at all and just shoots at bottle pressure.
