Oh wow, well in the nissan manual it states at 3000 rpm's the pressure shuld be wetween 51-65 so that is what was making me nervous. When I drove it for an extended period of time it would dip to as low as 28psi at 3k, but usually stayed at 30psi. At 4000rpm's it was around 40psi. What else besides this dent could be causing the low pressure?
