The Edge Evolution CTS has been getting some buzz around the Diesel pool lately.
The CTS monitor has an option for a rear-view camera, although this will raise the price considerably. If you’ve got the green, it’s worth the cost.
The Edge Evolution CTS doesn’t have as much power as a custom chip 
might, but it has other exclusive features that cause you to forget about that. For instance, the programmer has the ability to monitor up to eight parameters at once.
One more thing: do not assume there is a temp sensor on the manual transmission; you would be mistaken. You are required to install a sensor to read the transmission temperature. There is, however, a temp sensor in the auto version.
