Great little device to quickly maximize your engine's performance. I have not gotten to the point of uploading any custom tunes, but I do like the ability to make minor corrections to the PCM for variables such as tire size and having a diagnostic reader available as well. As for the performance increase, IMHO it is an accumulative difference. Meaning that it seems much more noticeable with other bolt-on mods (CAI, headers, etc)

Great monitoring device. Easy setup. Expensive to add egt or fuel pressure sensor

The scan gauge does everything is said it would. Bought to monitor water and oil temps but watching the MPGs is really interesting and taught me some new driving habits. I did have one problem setting it up and customer service was fantastic.
