Tuner is easy to use. Major power difference. With doing the dual exhaust this tuner gets awesome HP.

I was extremely impressed by the differance this tuner made on the drivability and overall power of my 2004 Chevy Silverado Z71 5.3 with 120,xxx. I had already installed a k&n cold air intake, flowmaster exhaust, and a poweraid throttle body spacer and was averaging 13 mpg city and 18 mpg on the highway but with the diablo sport tuner installed on the 91 octane tune im now averaging 17 in the city and 23 on the highway! Its rediculous to say the least. I recomend this product to every one I know. With gains like this why wouldnt you have one???

If your looking to get a programmer but not wanting to mess around with custom setting this is a good choice. If you have an automatic Dodge a programmer is a must as it cleans up the shift pattern and makes towing a much better experience. This programmer also allows you to monitor in real time such things as boost, transmission temperature, etc... You can expand this programmer which is nice if you want to take it a step farther.
