Save money, better in the trash!

Used on 3.6L Challenger. In a nutshell. DO NOT SPEND YOUR MONEY. I followed the instructions completely and carefully. Even after manually resetting the ECM, I still didn't see any improvement. No increase in performance or fuel savings. The return window is closed. I wanted to give this thing time to really "work" or take a break. Disappointed with a broken window product and such a small return window. waste of money!
