Tuner for speedo correction

Reviewed By Roger G (SAINT SIMONS ISLAND, GA) Reviewed for a 2004 GMC Sierra —7/2/2015 4:55 AM

I was very pleased with the ease of use of this tuner. I bought for my speedo correction after a rear end gear change and a tire change. When I programmed everything the speedo was dead nuts on to my GPS. 5 miles later my ABS and brake warning lights come on. Called hypertech... said it was a known fault of the abs gm computer and I would have to continue to input tire size until I got within 10% of the front to rear wheel speed. I dropped it 1/2" and speedo is off by 1.5 mph @60mph. Recommend

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!
