I asked around and was referred to these guys for my 2003 Dodge Ram by several people including one who is a diesel mechanic. I do most of my own work on almost anything but needed a diagnosis/second opinion on a fuel problem. Todd had my truck checked out the next day and gave me a variety of options. Very helpful and straight forward. Accurate diagnosis with solid reasons and data to back up the conclusions. I will be using these guys again in the future for my needs. No doubt.
