Review on 🚀 Enhanced Performance Chip/Power Programmer for Nissan 350Z & 370Z 3.5L and 3.7L - Boost Fuel Efficiency, Save on Gas & Maximize MPG, Amplify Horsepower & Torque! by Patrick Gibb

I have to admit I bought it because my auto mechanic neighbor did it too, I helped him install it and we put it to the test, which isn't it is cheap. We did 4 runs and this product made ZERO difference in his 370Z. I refused delivery and received a refund. Learned from my mistake before he robbed me of my hard earned money.
