I'm going to make the change. I am positive it will improve 0-60 time, it's just a question of how much. If I have problems and the change is worthwhile I'll sort them out. I have done several mods on my 4.6 where I have had no benchmark for results or nothing to base it off that someone else has done. If it is a mistake it certainly won't be the first time I was wrong about something intended to improve performance.

This has been very worthwhile to help me sort out why I have been procrastinating. A major part of it was the beyond terrible experience I had installing the Seicane audio system. It still won't play DVDs. Going to audio shop this week to see if they can sort it out and get all behind me. Thanks for all the input.
