  1. I couldn’t be more happy with this purchase! I installed it very easily in my 2020 Nissan Murano SV and it worked amazing! My mpg’s bumped up and the throttle feels way more crisp compared to factory. The reason I bought the chip was because the acceleration was a bit sluggish. After installing I noticed the difference after about 100 miles. I highly recommend these guys if you want to fix the acceleration response and mpg’s!!

  2. so far so good it…….when I have to fill it up again will be the final thing. oh and it is great on acceleration and torque but need a little more info do you run 93 to get better performance and what is the top speed now that the stage 3 is installed

  3. Just received my programmer today, haven’t had it 12 hours, drove 4 miles and it does great, you guys sell front end parts? Told all by buddies about it.

  4. Stage 3 Chip
    Amazing. Truck feels brand new again. Everything is crisp. My Sierra has 175,000 miles on it and in great condition. I had no idea how asleep the motor was until I installed your chip. Mid rpm the power just continues to grow. It runs like a new truck.

    Thoroughly happy with this purchase and I highly recommend it.

  5. I ordered a Chip because my Truck a Chevy Silverado 4.3 V6 with a 175,000 miles on it was bogging out when I gave it a lot of Throttle and to my Amazement it instantly ran better and better. Unreal! I would have paid $300 gladly!! Try it!!! 5 stars!!!
