FYI you have to chrono with .25s if you'll be using .25s
GBBRs build up higher pressure when using heavier ammo, so the fps to weight comparison isn't a linear scale like it is on AEGs
So if you're shooting 1.34J with .2s, you may very well be shooting 1.55J with .28s

Unlike an AEG, an easy way to raise your muzzle energy with a GBBR, is to use heavier ammo

Also, the #1 cause of low FPS in GBBRs is actually poor lubrication. Any new pistol or GBBR, I'll gain 20-60fps just by cleaning and regreasing it with high end synthetic grease
