How much lift do you get?

In the front of my yota, I bagged it where the bags are smashed to their limits when the truck is laid out. When i lock it up with 175 psi i only get 6 1/2 to 7 inchs of lift. This sux because i am body dropped so i have to clear the fenders for turns. I have phoenix bags and 2" drop spindles. WTF this sux! Everyone tells me to get slams if i want a lot of lift and use a lower psi to get it. What do you think? How much lift do you get?
