Me Too!
I had to put a new one on my car in April- somehow the old one got "empty". I put the air injection tube in toward the middle of the car, where it's not as visible. I was afraid the local inspection "gurus" would want to know why the air injection wasn't hooked up! Sometimes those guys are so clueless it's scary! Fortunately, the car passed, with no comments, no questions, using the stock chip with my 30 lb injectors and the 160 T-stat.
