What make spring are you ussing?An M150 spring should be giving you at least 500fps or more,plus the bore size and length should give you some more FPS also.Im assuming your barrel length is greater than 450mm.I like to use full cylinders for this length or greater.If it isnt full you really need to get one.Compression test your cylinder assembly,and check the nozzle to hopup for leaks.You will want a fairly hard bucking for this.My suggestions are Systema,or Guarder 60 degree.If ussing stock gears expect them to fail,and when they do then replace.No need to change motors if you have the Systema
You will definately need a larger battery to bring your trigger response up,and to fully realize that Systema motors full potential.For NIMH batteries 9.6v or 10.8v at nothing below 4000mah is what I would use.Or simply upgrade to 11.1v 20c or better lipo's.You can increase your range by getting either a 6.03mm or 6.05mm inner barrel.As stated previously,range is negligable past 509mm in length.
I read nothing in your initial post about AOE correcting,checking shimming,etc.Has this been done?If not,this needs to be at the top of your priorities list.
