Just got my V1 3.861. I joined this forum to learn how to use it. So far, great amount of information on this forum and I find it very helpful. I came from a forum where if you don't search for answers you will get flamed (my.is). Got my IS300 a V1 recently. Loving it so far but having doubts about its tune-ness. I might send it in soon for a tune. Still doing research! Hope to help and get help from this forum!
