VLocity

Fast cycle
Better Efficiency
Weaknesses:
Hard to install.
Review:
It makes my ion cycle a whole lot faster. I was shooting around 20 without it, and now its up near 25-26. My VLocity has trouble keeping up with my ion now. It is a pain in the ass to install, i ended up having to cut the body back a little.
Conclusion:
Great for anyone who's looking for a cheap upgrade that pays itself off many times.
