I know there is a lot that factors into my question, but I just want to know what people run to give me an idea of where to start with the LQ4. I think I'll start with about 14*-15* without the meth and work my way up from there. If I can make good enough power without pushing the timing up really far, then I'll just leave the tune at that (a little conservative) then dump the meth on top of it. That's how I did it with the 4.8L and it made decent power without a hiccup.
