Works great!

Reviewed By steve f (blaine, MN) Reviewed for a 2011 Chevy Silverado —1/26/2015 6:45 AM

I have been using my Range device now for Two weeks and it is working trouble free. No more goofy sound through the exhaust. No more weird shifts out of the transmission. Best of all, no change in mileage!!!

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!

Scan Gauge

Reviewed By william s (Fairbury, IL) —1/15/2015 10:14 AM

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.
