If your loved one is driving you nuts housebound from the stay-at-home order, get them a fuel injection manual or tuning calculator to keep them busy.  We can help them with outrageous racing improvements like determining the fuel system for adding a blower or nitro or more boost for more power!  If you are the one driving your loved one nuts, ask them to get you a book or the calculator.  Great gift for father’s day, birthday, or special occasion.
