Turned off the DOD on my Avalanche and gave it just a little more power. Added some pep in its step.

After receiving the tuner, I updated through "ignition". Plugged in to my port, and could only get 12% download from stock settings. Called Superchips, got 5 more updates, had to unplug 2 radio fuses,and worked great. 3 to 4 mpg better on economy setting without losing power. Am going to try towing mode, and hope for good results as well. Good product, very good customer support!

Easy to install but be sure to follow instruction. (Pull proper fuses). Disconnect (8-4 cylinder) drop out. You will have a smother , quieter and more responsive engine. There are also two options to try the premium option and the regular option I have yet to try their premium option but I am very satisfied with the regular option. For my money it was well worth it.
