OK, I want to throw out a plug and clear the air for the guys out there @ Aeroforce, First I want to apologize for my comment's in an earlier thread that I had removed. I should have read the instructions and Emailed them instead of posting on their sights forum. I did get in touch with them, and they were very helpful clearing up the issue I had with my guage. A new guage was sent out and should be arriving in a day or two. Again they are very knowledgeable and have great service.
