Have to turn the VLo almost all the way in to get it to crony.
I felt the difference as soon as I aired up after the install. Less kick back, better air use, and faster cycling. Once i got out on the field i had better shots and more bps by about 2 or 3. It looked like my distance was better and had breaks on longer shots using the same paint as before the install.
this is a must to upgrade your A5 you will notice the difference right away
