Awesome programmer, 1 problem

Reviewed By Corbin S (PLEASANT GROVE, UT) Reviewed for a 2003 Chevy Silverado —12/25/2017 8:41 PM

Love the programmer. Clear screen, easy to use, but has 1 fairly big flaw. I have to remove 5 fuses from my fuse box every time I change the tune. Not a huge deal, but still... That sucks. Otherwise I love it!

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
