How would you like to boost your power by 35%, your torque by 25% and your gas mileage by 15%? Sounds good, doesn't it? This is the Nitro-ODB2 ECU chip box. It claims improvement in mileage, power, and torque after about 200 miles in use. Only time will tell, though for five bucks, you aren't out a lot. I am excited to try this out and see how it does in my Acadia. I have seen these for sale for much much more so what the heck, let's give it a shot.
