Anyone know where a "Star" spring 140% would fit on the spring comparison chart? PDI 140 perhaps?
I've been searching the internet for a day now and can't find any info.
I don't want anything over 400fps since I use this gun outdoors.
Here's the link to where I'm buying it. It's all in Japanese since that's where live. The advertisement does not give any info.

Yes I know about the 1J limit out in Japan. I play with a team in a private location and we all have guns upgraded over 1J. They cracked down on AEG's about 5 years ago when some retarded kids thought it would be funny to shoot some 90 odd year old homeless guy with their M170 loaded spring guns. They ended up killing the guy. Now we are all suffering for their stupidity.
Thanks in advance
I should say that my gun is highly upgraded in other respects.
6.03 prom tightbore
prom cylinder head
Systema Advance piston
prom torque up gears
metal bushings
bearing spring guide and piston head
I'm looking to achieve about 350-380 FPS with .25s with 400 being an upper limit with .2s.
