Help with Firestone Ride Right

I recently have done some work to my 2013 TRD Sport LB. I added level kit (HellBent 2.5 to the front) added some Procomps and some All-Terrain 265/70/17's. I have recently in the past 2 weeks added the Firestone Ride Rite bags to the back. It still has a slight rake (which I like) and only put the bags on because when weighed down it sat on the bump stops and rode bottomed out. Now my question is during normal driving I have tried between 5-25 psi to try and figure out a good driving pressure, but no matter what I do when I hit a bump or dip if pressure is high (15-25 psi) it's back breaking (obviously!) but then I try to run 5-15 psi and still feels like I'm bottoming out. I have the stock Bilstein shocks and wondering if this is the case. Do I need to upgrade to 5100's or 5125's. Not sure where to go with this. I want to try and get the stock ride feel back and need some input! Thanks!

 

I've noticed that when I went out on a shooting trip and loaded it down with weight and then aired the bags up to 50-60 psi and drive off road with all the gear it rides and handles like a champ. I don't know if that will give any insight to how to fix the problem.

 

15 psi for light loads, 30-40 psi for heavy loads... I also had Bilstein 5100's installed on the back. This was on my 2005 DC. My 2010 DC does not bottom-out, so no need for the Ride Rites on it.

Very important to not add more air than needed to level the truck. People who maxed out the Ride Rites broke the frame of their truck.
