tuners guide?

Ok this might be a touchy subject but is there a site/youtube or help for tunning??

I have deleted just about every tune i have bought to make me learn how to do it?

I dont have alot of hours free time as i work 12 hour days and have a wife so i relly need 48 hours in a day lol

I dont wish to have to ask for tune theres loads of good tuners on here who have helped me but id like sort of the basis or a pointer were to look or basic setup so i can learn/copy/mod some tunes for myself and sf lol

any help please looking for race and drift but know others would like playground and drag tunes

cheers peps

Here's a link to one that's been in the TAC section for awhile. There's a build guide for hotlapping and a tuning guide from FM.net
