Kept from trading.

Reviewed By Robert A (Huntington, WV) Reviewed for a 2011 GMC Yukon XL —2/4/2014 6:10 AM

Do not like blue glow in car after dark, did stop the stall I was having when it went from 4 to 8 cylinders. It hurt gas mileage a little. The Yukon does seem to accelerate better. It was very easy to install. I am satisfied with the fact it makes me attain the full motor I paid for all the time. I feel it has kept me from trading my car do to lack luster acceleration.

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.
