Comparison Reviews It is useful to have a neutral party review these scam-ridden products, so thank you.

Thorton chip tuning I received the tuning chip on 1/25/23. It is now 4/29/23. I have had the chip plugged into my car the entire time. Doesn't work. Doesn't improve mpg nor does it give my car more hp. I'm convinced it's a scam.

In manual it says after two weeks it will work properly. I will share my second week.
