Does what it says

Reviewed By Taylor M (MESA, AZ) Reviewed for a 2014 GMC Sierra —1/26/2015 9:06 PM

2014 GMC Sierra 1500. Fairly easy installation. Manual days you need to remove several fuses, but this is not necessary. Just make sure headlights are off, radio is off, and nothing is plugged into DC outlets. Did what it said!

Does what the local Chevy dealer is unable/unwilling to do.

Reviewed By Glenn B (Owingsville, KY) Reviewed for a 2001 Chevy S10 Pickup —1/26/2015 5:58 AM

After swapping the rear end to a higher gear ratio, I took my truck to the local Chevy dealer to have the speedometer calibrated. They told me that they did not have the codes needed to reprogram to reprogram my truck and that they could no longer get the code. After plugging this little programmer into my computer and downloading the codes it needed, I had my speedometer calibrated in less than 10 minutes.

Very Easy

Reviewed By Mark R (RED FEATHER LAKES, CO) Reviewed for a 2011 Dodge Ram —1/17/2015 8:26 AM

This was a VERY easy install......Instructions are straight forward, and it literally took me 3 minutes to install the first time.
