    QUALITY WORK

    I drove all the way from the coast to visit Grumpys Performance Center. When I got there I found a family business that knows its stuff about engines. They were very knowledgable. I had them put a 454 in my Chevelle and the car is still a beast on the road. It runs good and is fun to drive. I recommend to anyone.

    They rebuild a 5.9 dodge cummins for me a few years back. The engine has 47k miles on it now and the truck still runs like its new. never had a problem.

    I strongly do not recommend this business

    My personal experience was unfriendly and dishonest,they did unauthorized work, denied wrong doing, threatened additional costs, and made fraudulent costs to lien vehicle.

    Dishonest Business Ethics

    It is my personal experience that they will do unauthorized work, deny wrong doing, threaten and add fraudulent costs to lien your vehicle.
