You can guess by the fact that my truck died about 3 months ago that some stuff may have happened since then. I'm thankful to all the guys who post here regularly who actually know something. I would have screwed a lot of things up in a big way if they hadn't. Last night after I finished with some tweaking of the project, I clocked a 7.7 0-60 on my cts. I'll get some custom tunes in a couple weeks and see what changes. Pictures will be forthcoming.
