so I just got a new car and it has air ride with a nitrogen tank no compressors. how long dose the nitrogen tank last when you raise and lower your car every time you drive? what psi should I refill the tank? what psi is the tank full? when you park your air ride car should you lower it to take pressure off the system or it dosnt matter? if you hit the switch up a little to long could you pop a bag or line or anything?
