Review on 🏎️ Increase Nissan Cube 1.8L Performance: Innovative Performance Chip/Power Programmer - Boost MPG, Horsepower & Torque, Save on Fuel! by Jerry Delic

Very disappointed. It requires identification and connection with a pair of wires, and if they're wrong, who knows what will happen? If these are correct, it is a very expensive technology. This does NOT apply to my vehicle. It is necessary to leave the battery unplugged, preferably overnight (I see "why", they just didn't say it online). Then up to a week before showing any real results. If performance claims are as imprecise as ease of connection and specificity to your vehicle, fine. Since there are no reviews yet, here is the first one.
