Good company
I bought the stage 3 chip and it made a big difference for my 2018 Chevy Impala. I was so impressed a ordered one for my girlfriends 2017 hyundai Elantra. I am on a fixed income and decided to put it on hold for a month because an unexpected bill came. 12 hrs after I ordered they refused to cancel it. That sucks. Otherwise I said, I like the chip. Had one from another company a couple of years ago and just made a tad of a difference. This is the computer chip for you. Just don't try to cancel it because it won't happen.
