Did you floss or teflon tape the rubber onto the barrel to get a good seal inside the hop up? a good amount of fps can be lost in blowby if the barrel/rubber assembly is not tight int the hopup.

According to the spring chart here:
Spring Comparison Chart PDI 150% spring supposed to be giving out 395.45 FPS. The field I play at doesn't allow anything above 400FPS so I have to be in this limit...
I only did teflon tape over barrel and rubber and then teflon tape over the hopup and barrel. Will try again with the floss...
Actually one thing I changed while changing nozzles is I replaced piston head from SPEED to Lonex, because occasionally I was getting shots less than 100FPS and suspected that to be the piston head issue...
Thanks!
