cronoed my gun and it was at 144fps .. i adjusted the scew out until it almost fell out and it only went to 244 ... i was on HPA with good pressure .. the only mod is the polished insides and i was useing a remote ...there was a brand new BT ERC 4 and his gun was shooting slow fps to!!! Do i need a different spring ?

[BTWOSOGsnakebite]

yep u need a standard black spring the newer ones because of some european fps laws are coming with shorter springs

The remote may be bottoming out and cutting off your air to the gun. There is a mod where you concave the front part of the part the screws into the asa. Feyd.........

tried it with and without the remote ..same fps , I ordered spring kit

i like the red spring, its the heaviest and if you shoot fast it will give you the best performance.

Are you using a high pressure HPA tank?

Also the possibility that the asa could also be starving the marker.

be carful tho, dont use too heavy, the heavier the spring the lower your efficency, for best results use the lightest spring possible, only use a heavier spring if you absolutly have to.
