we have a HOLLEY system on our copo and they are very easy to work with and also offer a schoool at bowling green, ky to help you understand and allow you to tune the system and be confident about your lap top tuning abilities. we have used other sytems one that works one that never did . I think the HOLLEY is the most user freindly and they are the best today. however other systems may not be freindly to the newer operating systems on the new laptops or computers for sale today, hope this helps in making the best choose for your application and good luck.
