    31003 is rated 3.4 out of 5 by 7.
    Rated 5 out of 5 by from Big difference from a carburetor It was getting increasingly difficult to keep my carburetor in tune and there was always some area that suffered. Either idle leaned out or full throttle would be too rich. Decided to quit fooling around and get a system that kept everything in check. This unit blows the carburetor away in terms of responsiveness and mixture control. It just keeps pulling! Fuel mileage has increased and the power is always right there. Wish I had started out with FI TECH

    Rated 1 out of 5 by from Do not buy!!!!! I purchased this system and installed it per manufacturer's instruction. Works great until my vehicle gets up to operating temp then it dies and leaves you stranded. I contacted the manufacturer and they told me to replace my entire ignition system because my ignition system was the problem. Guess what replaced all of the parts they recommended and it still will not run at operating temperature. So, I contacted Jegs to send it back and get my money back and they told me I altered the FiTech system by installing it and will not give me my money back. Don't make the same mistake I did.
