need to improve my 60ft

[luv2fast]

Hello,
I need some help adjusting my suspension for a better 6o' time, I currently run a consistent 1.35 60ft, but if you watch the attached youtube link video
you'll notice the tires squeel every 8-10 ft like the suspension or tires are hopping. Here is what I have:

leave @ 22psi
Coan powerglide with transbrake @ 5200RPM
4 link
Alston rear anti-roll bar set at neutral on both sides
QA1 9 way adj. set at 2nd from max
springe rate-dont remember
31x18.5x15 Quicktime pro's at 7.5 PSI

any help would be great

My $.02...

1. Tire pressure that low may be causing the tire to wad up in the ft, and U R "driving over the lump". AIRC, Hoosier recommends something in the 12psi range to start with..Adjust as needed. [A GOOD video of the tires is a help. Get the vids up closer, and from the side, if possible.]
2.QA1 setting?? 2 cliks from tite or loose? Double adjustable?
How old are the shocks? Some QA problems are due to mis matched performance. Have these been dyno tested?
3. Wheel size is?
4. Instant center is?
5. Antisquat % is?
6. Segment times are?
