I weigh 165lbs. Whats a good pressure to run, the frame in an 03 medium. With 70lbs, it bottoms out even off a curb.

I took the information below directly from the manual located at the below URL hope it helps

Your Specialized bicycle features a FOX Racing Shox FLOAT R with BRAIN Technology. This technology senses
bumps in the trail and activates the suspension as necessary giving the rider the efficiency of a hardtail with all the
benefits of a full suspension bicycle.
To optimize the performance of the shock, it is important to set it up correctly. Taking the time to tune the spring rate
(air pressure) and rebound damping (rate at which the shock returns) will greatly enhance the riding experience.
Because the shock defaults to a locked out position, the shock cannot be set up using the traditional method for
setting sag. For this reason we recommend that the initial set up be done according to the air spring chart below.
Find your weight range on the chart below and set the air pressure to the corresponding value. Take a shock pump
along on the next ride and monitor the performance of the shock. Slide the travel indicator o-ring up against the
scraper lip before starting to ride. This will help show how much travel is being used. If the shock seems to bottom
excessively, increase the air pressure by five (5) psi. If the shock seems too stiff or if full travel is not achievable,
decrease the air pressure by five (5) psi. The goal is to use the full travel of the shock once or twice on each ride. Full
shock travel is 1 7/8 inches +/- 1/8 in (48 millimeters +/- 3 mm). Much of this depends on the terrain and one's riding
style so take these into consideration during the set up process.
Rebound damping controls the rate at which the shock returns after it has been compressed. The red adjuster dial
can be turned clockwise for slower rebound and counter-clockwise for faster rebound. There is a wide range of
adjustment enabling the rider to tune the shock to any air pressure and riding condition. The proper rebound setting
is a personal preference and varies depending on rider weight, riding style and riding conditions. As a general rule,
rebound should be as fast as possible without kicking back and pushing the rider off the saddle when riding the
bicycle in rough terrain. If rebound is too slow the suspension will not function properly and the wheel will not follow
the changing terrain. Determining the proper rebound setting may take a number of rides. Use the "curb test" to start
dialing in your rebound setting. Do this test on flat ground where there is little auto traffic and plenty of room. Ride at
normal cruising speed and stay seated. Ride off a curb and monitor the rebound. If the bike oscillates a few times
after landing the rebound is too fast. If the shock does not return promptly it is too slow. Start with the dial in the
middle (about 12 clicks from full slow) and adjust 4 clicks in the direction needed. Single clicks of adjustment can be
used to fine tune the rebound damping. During the first few rides, adjust the rebound damping and note the different
ride characteristics. Your rebound damping setting may change with different riding conditions.
Air sleeve service can be performed as on other FOX Racing Shox FLOAT rear shocks (see pages 10&11 for details).
The strut must be removed before removing the air sleeve. A 22mm open end wrench is required to remove the strut.
Torque to 175-200 in-lb (19.5-22.5 N-m) when reinstalling. A 22mm crowfoot attachment and a torque wrench are
required to install the strut.

Rider Weight

100 -110

There are alot more weights listed but this is for the weight you need. And remember these are guidelines play with it as you need.
