I installed my S&B filter about a week ago and everything was going just fine. We went on our first camping trip this weekend and again the filter did just fine. As a side note, 3rd gear close to red line pulling up a steep hill with a constant 30 psi of boost, is almost ear piercing...but I digress.
Anyway, we unhooked, and went for a drive. We were going up a slight grade, running about 10 psi...then she went up to 15 psi...and dropped to 5 psi with this small bang sound. My wife commented on a slight smell that went away very quickly. I didn't think much of it...finished the day out with a couple of key cycles. The next day on the 2nd key cycle the CEL popped up. My questions is, should I be worried (I don't have anything to check the code) and any suggestions of what it is? Thanks
