Hello :)

Hi guys I’m new to the forum, been reading a lot of useful info on here so thought I’d say hi.
I bought a stealth 2000 .22 (non fac) about 2 weeks ago, really love it.
After a bit of research I noticed a lot of people modding with leupy custom mods so decided to give mine the treatment, I purchased leupy hybrid hammer,mainspring,spacer and spring centraliser.
After moving old spring, hammer and pretension packer, I fitted new spacer, centraliser,spring and hammer only to find power had dropped to around 6ftlb, was really confused by this as I was warned power may increase with new components!!
Tophat is standard brass face valve type, any help on how I can get the best out of my stealth be much appreciated, thanks
