If you are using one, how much air are you putting in it. Is it something you need to try different air pressures in to see what works best? If so, how do you tell what works best? Do you look for changes in your 60' times?

I read people using between 10-20 lbs.

I am using 12 psi in mine but now that I have installed a 1LE anti-rear sway bar I might not even need an air bag. If you have enough loading to keep both rear tires planted evenly you don't need an air bag. I'll try 5 psi next time out and if I hold traction I'll remove it.
