Big difference in power. I get 3 to 4 mpg more when using performance level.

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
