You should be able to see if the nozzle is fully going into the hop up unit when the bolt is out if you look into where the gas goes in from the mag to the blowback chamber there is a piston in there with a rubber head or seal that could be worn or torn.
The nozzle could be chipped or cracked also the bbu could be cracked.
Edit what fps did it have befor cause the stock rating is
280 FPS (HFC134a Test @ 25°C Room Temperature)
Recommend / 390 FPS (Top Gas Test @ 25°C Room Temperature
There is a high power bolt as far as i know and also there are high flow valves and ratech makes a cpl bolts and an npas so you can adjust the fps.
Why do you want it so high anyhow you cant use above 350 indoors and 400 oitdoors anyhow. And that measured with 0.20bbs
