  1. 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.

  2. 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.

  3. 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!!!

    • Hi Charles! I am so happy you enjoyed our product! Spread the word!

  4. Works great Watch out for transmission slippage

  5. I notice a difference almost immediately after installation.
    Better fuel economy and quicker acceleration were very noticeable.
    I highly recommend trying this plug and play programmer. You won’t be disappointed!
    I have told sooo many people in my area and they have all tried it and are very happy with the product. 👍

    • I appreciate your kind words Gene!!
