if your sled is stock otherwise, meaning the only mods are reed spacers, your probably going to end up around a 48/36 helix.

while you're in there to install reed spacers, pull out the reed cage and inspect the reed petals. if they are getting chipped on the tips, or kinda bent, where they don't seal anymore, like a .020"-.030" gap, then i would suggest replacing them w/some carbon tech reed petals.
