Hey i'm going to be tuning a buddy's truck soon and i wanted to get a little advice. i'm going to remap his ve table and do all the normal stuff but i was wondering what kind of spark advance the 6.0 likes at wot. I have my 5.3 running pretty good but i don't have any experience with the 6.0. the other question i have is in regards to the trans, i haven't worked on a 4l80e either but figured i would bump up line pressure a bit and change shift times to around .2 seconds. i have the 4l60e figured out, but i'm just wondering how much of that stuff transfers over to the 4l80e.
