So I've been reading up on modding my gtp I have what I think is a nice plan of attack laid out and then I start to think about tuning. After spending some time on the hptuners forum and here I've come to the conclusion that I don't even know where to begin when it comes to tuning lol. Is there some resource(s) that breaks down not only how to go about tuning but also like the super basic stuff. Like I'm reading through Jerry's tuner notebook and I can't make heads or tails of it.
As a tack on question, is it possible/recommendable to build a decently fast gp (13-12's) w/o knowing how to do your own tuning?
