Let them tune it? Were talkin about a hobby car.. not his daily driver!!
Whats the fun in him doing it for ya? LEarn it the hard way! You cant break anything..
My engine was giving me hell.. but I am starting to understand it pretty well and nw I can listen to it and tell if its rich or lean.
Practice is the key! Dont let other do it for you!
Thats my approach anyway
