Hey guys need some help.

So I bought the novritsch tuning kit for my Vsr-Gspec. After taking it to a site and shooting hot at 530fps I had to cut my spring and was then shooting 511fps. since I changed my hop-up to a action army unit and barrel spaced my barrel. I went back to another site and got it chronoed again shooting at 560-570fps. How can this be after selecting the 500fps spring and cutting it down.
But what would be the best spring for me to buy to keep as close to 500fps as possible?

All help appreciated
