It sounds like you had a longer than stock length inner barrel, no?

In my experience, inner barrel lengths greater than 112.5mm (stock length for a Hi-Capa 5.1) give the greatest FPS boosts. With a 6" barrel, you can easily see 360-370fps, and with a 7" barrel, you can see 380fps or more. With 0.25g BBs, you'll be pushing power equivalent to over 400fps with a 0.20g BB.
