Couldn't of asked for a better setup. Local shop wanted over $1000 to replace my old busted flowmaster exhaust. Glad I found the Gibson exhaust for a great price.

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

Looks great love the nice low profile only thing I did care for was the clamps that hold the brackets to the bed rails I ended up getting some nice stainless hardware and bolting mine in
