What's a good starting point to work with? I've got about 21psi in it right now... anyone have a general idea where to start?

I know it's different for every car, just don't want to be way off my first couple runs

 

No more than 15. I bet if you pull the air bag out you'll see that it's stretched now.

 

Really? Is that bad? I read on here that someone uses about 20 and read others using around 20 as well

Had the car on a lift today for a minute and took a look at the bag, looks ok..


hmmm i'm confused.

 

You'll likely find 25-30 is what your car will want. Mine needs 30, some setups like 25. It's just a matter of trial and error until you get to what your car needs.
