setting 3 economy

Reviewed By Jack D (MORGANTOWN, WV) Reviewed for a 2003 Chevy Silverado —8/9/2016 5:50 AM

most of the people will buy this for more power but i got it for the economy mode is ask for you to use regular (usually 87 octane) so i had to run it on setting 2 until i filled up on 87. Am know running it on setting 3 but with both setting it changes the shift time from factory and with the mile coach it shows me around 23 mpg but it also account for costing with i can do a lot off in WV all and all if you by it sooner then latter it should save you money if you watch the mile coach

It's not that bad of a chip. I was getting 11 mpg and now I'm getting about 16 but I'm also running premium gas now so....there isn't that much difference horsepower wise either. I'd probably go with a different brand if I was buying another one
